Body builder guidelines 2007
Body builder guidelines LT
The body builder guidelines define the requirements for custom body builders and equipment fitters designing and
mounting bodies or performing conversions to base vehicles of the Volkswagen Commercial Vehicles brand.
The body builder guidelines must be strictly adhered to when performing any modifications to the vehicle.
Ensure that no modification adversely affects the functional reliability and safety of the running gear, the body or the
electric system. Modifications must only be performed by qualified specialists and in accordance with the generally
acknowledged rules of the automotive industry.
Prerequisites for modifications to used vehicles: The vehicle must be in a good overall condition, i.e. structural parts such
as longitudinal and cross members, pillars etc. must not be corroded to such an extent that structural stability might be
adversely affected.
Vehicles whose modifications might affect the validity of general certificate of roadworthiness must be presented to an
authorised testing centre for approval. It is recommended to clarify in advance with the relevant authority whether approval
is required.
When inquiring about planned modifications, please enclose two sets of design drawings of the complete scope of the
modification, including weights, centre of gravity and dimensions, which also clearly show how the body is attached to the
chassis. Please use the online contact form:
http://www.vwn-aufbaurichtlinien.de/de/kontaktformular
Please also provide information about the intended operating conditions of the vehicle. If bodies, installations or
conversions comply with the present guidelines, no additional approval by Volkswagen AG is required for the presentation
of the vehicle at the relevant authority examining roadworthiness.
The work safety regulations of the trade association and the EU machine directive apply.
When making modifications to vehicles, all corresponding and applicable legal regulations, rules, laws and directives must
be observed.
Note: Subject to errors and technical amendments. The electronic version of the body guidelines is the decisive source of up-to-date data on body guidelines (online body
guidelines). Data status March 2009
1
The body builder's or fitter's warranty conditions apply to the body builder's or fitter's scope of supply. Therefore, warranty
claims associated with complaints to this scope of supply cannot be made under the warranty conditions applicable to
Volkswagen Commercial Vehicles.
Volkswagen vehicles delivered after 01. January 2005 are covered by a 2-year warranty without mileage limitation for the
flawless condition of the product (Volkswagen warranty).
Defects of bodies, installations and conversions provided by third parties as well as defects of the vehicle caused by the
said bodies, installations or conversions are excluded from the Volkswagen warranty and also from the Volkswagen paint
and body warranty. This also applies to accessories which were not installed and/or supplied by the vehicle manufacturer.
The body builder or fitter is solely responsible for the design and assembly of bodies and the execution of conversions.
All conversions must be documented by the body builder or fitter in the service schedule provided with every Volkswagen
vehicle.
Due to the multitude of conversions and diversity of operating conditions, the information provided by Volkswagen AG is
subject to the reservation that modified vehicles are not tested by Volkswagen AG. Modifications may affect the properties
of the vehicle.
For reasons of liability, the body builders or fitters must provide the following information in writing to their
customers:
"Due to the modifications* to your Volkswagen Commercial Vehicles base vehicle, the properties of your base vehicle may
have changed.
Please understand that Volkswagen AG does not assume any liability for any negative effects resulting from the
modifications* to the vehicle."
* At this point, the term "modification" may be substituted by a more precise description of the work performed, e.g. by
"camping equipment installation", "wheelbase extension", "box body".
In individual cases, Volkswagen AG reserves the right to demand proof of the information being passed on to the
customer.
No general legal entitlement for the approval of a body modification exists, even if such approval was previously granted.
Bodies, installations or conversions complying with the present guidelines do not require additional approval by
Volkswagen AG to be presented at the authorised examining body.

Extended storage times cannot always be avoided. The following measures are recommended to ensure that vehicle
quality is not affected by long-term storage:
At vehicle delivery:
• Fill tank
• Do not park the vehicle under trees, poles; etc.
• Open all ventilation flaps, set blower to maximum speed
• Disconnect battery(ies)
• Remove dirt, snow and moisture from vehicle (footwell)
• Close windows, doors, front lid, rear lid and sunroof
• Put manual gearbox into 1st gear or lever of automatic gearbox into park position. Do not engange reverse gear.
Do not apply the parking brake.
• Remove the windscreen wiper bags and prop up the wiper arm using a foam pad, remove any loose protective
film. ("Aero wipers": remove and store in suitable location inside vehicle).
• Check tyre pressures; increase to 4.5 bar for commercial vehicles, if required.
Check vehicles weekly for contamination by aggressive media (e.g. bird droppings, industrial dusts) and clean, if required.
Check battery open-circuit voltage every three months. Open-circuit voltage means the voltage of the disconnected
battery after a minimum storage period of 12 hours. Recharge battery in due time before it reaches an open-circuit voltage
of 12.4 volt ('magic eye' changes from green to black). Batteries with an open-circuit voltage of less than 11.6 volt are in
state of exhaustive discharge and should be disposed of soon.
Batteries must be recharged only with current-controlled and voltage-limited chargers. A maximum charging voltage of
14.4 volt must not be exceeded.
It is recommended to check the tyre inflation pressure every three months and to increase it to 4.5 bars for commercial
vehicles, if required.
Reconnect battery negative lead(s) before recommissioning the vehicle.
3
Fitters of accessories and body builders must ensure that they comply with all applicable environmental rules and
regulations, especially EU directive 2000/53/EC concerning end-of-life vehicles and EU directive 2003/11/EC relating to
restrictions on the marketing and use of certain dangerous substances and preparations.
The vehicle owner must keep all assembly documentation concerning the modification and hand them over together with
the vehicle to the dismantler. This ensures that modified vehicles are processed in compliance with environmental rules
and regulations at the end of their lifecycle.
4
Maintenance instructions or service schedules outlining inspection and servicing work should be provided for the
modifications performed by the body builder or accessories fitter. These instructions or schedules must include the
maintenance and inspection intervals as well as the required operating fluids and materials and the spare parts. Parts and
components with a limited service life which must be checked in regular intervals to ensure service reliability and timely
replacement must be explicitly stated.
This should be supported by a repair manual including tightening torques, settings and tolerances as well as other
relevant specifications. Special tools, including their source of supply, must also be stated.
The manual must also state which type of work must be performed only by the body builders and accessories fitters or
their authorised workshops.
If the body builders or accessory fitter's scope of supply includes electric, electronic or mechatronic, hydraulic or
pneumatic systems, circuit diagrams and diagnosis routines or similar documentation facilitating a systematic search for
faults must be provided.
5
Body builders must ensure that the fitted components, conversions, bodies and modifications comply with applicable legal
rules and regulations as well as all regulations regarding work safety and accident prevention. All safety rules and the
information material provided by accident insurance providers must be observed.
All technically feasible measures must be taken to prevent unsafe operation.
Country-specific laws, directives and approval regulations must be observed.
The body builder or device or equipment manufacturer is responsible for the compliance with these laws, rules and
regulations.

The weights and axle loads (permissible/empty) for the LT attachment variants - box-type delivery van, chassis with
cab/double cab, can be downloaded in the download area, together with the appropriate drawings. For the chassis with
cowl (without roof and back wall), the weight has to be reduced by approx. 50 kg compared to the chassis with cab.
Note:
To ensure a sufficient manoeuvrability of the vehicle, the minimum front axle load must amount to 25% of the total weight.
In the case of vehicles with loading tailboard, the minimum front axle load must amount to 30% of the total weight.
The indicated unloaded-state weights refer to the standard vehicle equipment (including driver, spare wheel, tool and filled
fuel tank). Weight tolerances of +5% are permitted according to STVZO [German traffic regulations] and are to be taken
into consideration, where appropriate.
If extras are installed, the permitted unloaded weight increases. If required, the final unloaded vehicle weight is to be
determined using a scale.

The weights must never exceed the
• permissible total weight
• permissible front axle load
• permissible rear axle load.
When projecting attachments, it has to be ensured that a single-sided weight distribution is avoided - in particular if fixed
attachments are to be installed. If it is not possible to adhere to this recommendation, the single-sided load may only result
in a maximum difference between the wheel loads of 8%.
Note:
Observe the tyre load-carrying capacity!
Example:

The chassis dimensions are shown in the drawings. The drawings are available in the "Download" section. They can be
downloaded and used for planning/constructing.
When you are using tyre sizes which are differing from the standard equipment, the vehicle and chassis heights
(measured from ground level) may change. In this case, it is necessary to consider these deviations during projecting.
Important note:
• The minimum distance between cab and attachment must be at least 50 mm.
• The rear overhang of the attachments may under no circumstances exceed the default values indicated in the
following table.
• The distance between the rear edge of the attachment and the rear edge of the end cross-member/underrun
protection must not exceed 400 mm.

Numerous guidelines are to be adhered to, when chassis is to be transported on their own axles:
• Wheel cover
• Ballast weight for braking
• Lateral starting protection
• Lighting equipment
These parts are neither developed nor on-stock, thus making the transport on own axle unnecessarily expensive. For this
reason, the self-pickup of chassis is no longer possible. It is recommended to deliver the chassis by rail or truck.
15
For attaching a loading tailboard, it is required to consider the following instructions:
• The permitted rear-axle load must not be exceeded.
• Consider minimum front-axle load (i. e. 30% of the total vehicle weight).
• Check the stability.
• Calculate the load distribution including all extras.
• If required, shorten attachment length and rear overhang.
• Guide subframe as far as possible to the front and realise a force-locked connection with the chassis frame.
• Standard box-type delivery vans require no subframe.
• A stabilizer bar is necessary for the front and rear axle.
• If possible, use only hydraulic supporting devices. Do not lift the vehicle with the supporting device (chassis may
be damaged)
• Load distance max. 500 mm
• Security
The regulations for the prevention of industrial accidents and the EC Machinery Directive are to be adhered to.
Check for underrun protection and lighting devices.
• The standard vehicle can be provided ex-works with the required extras item 1.3).
Vehicles with double cab may only be provided with a loading tailboard in special cases. The mounting is only permitted
with the permission of Volkswagen AG.

For example, when working with a lifting hoist, the entire vehicle may be lifted on 4 hydraulic pillars -the wheels lose all
contact with the ground. Due to the heavy weight of the front of the vehicle, this causes impermissibly high tension in the
longitudinal frame members in the area of the front support.
A reinforcement of the chassis frame is essential for such applications. To this end, fit a mounting frame through the rear
wall of the cab under the base of the seats and secure this with an additional console and a bolt connection. A suggestion
as to how this can be implemented can be given on request by the responsible department.
An additonal battery as per PR-No. 8FV (location underbase of co-driver's seat) is not possible with this configuration and
also for the LT 46.
17
When laying out the loading crane attachments, it is required to observe - apart from the necessary stability - the
connection between loading crane and chassis (item 3.4).
Loading crane and vehicle attachment are to be arranged in such a way, that the permitted axle loads are kept in every
loading state.
Loading crane attachment behind the driver™s cab
• Maximum crane-load moment: 25 KNm
• Moments of resistance for mounting-frame side rails: Wx = 45cm3 (45cm3 (profile dimensions according to
diagram under item 3.3)
• Determine the flatbed length depending on the loading-crane attachment.
• Due to the load distribution, it may be necessary to lengthen the chassis.
• A permission is required for deviating crane attachments.
• The necessary supporting devices should be hydraulically actuated.
• Do not lift the vehicle with the supporting device (chassis may be damaged)
• Crane attachments and supporting devices must neither impair other equipment, modules, units, etc., nor the
associated functions.
• Loading crane attachments must meet the requirements of the regulations for the prevention of industrial
accidents and the EC Machinery Directive.

According to article §51b. of the German motor vehicle traffic regulations (STVZO), vehicles with a width of more than
2,100 mm must be provided with parking lamps when they are to be used in the Federal Republic of Germany.
As standard, all chassis and chassis with flatbed attachment are not provided with parking lamps (standard vehicle width
1,922 mm and 1,990 mm).
In the LT delivery program, the tipper with single and double cab as well as the LT46 Pick up with single and double cab
exceeds the pre-set vehicle width (standard width: 2,120 mm). At these vehicles, parking lamps are assembled in front on
the side on the cab roof. In addition, the outside chambers of the 6-chamber lamps at the vehicle rear are designed as
parking lamps (series equipment: PR-No. 6S1).
When ordering a chassis that is to be used for an attachment with a width of more than 2,100 mm, it is required to order
also back and front parking lamps (PR-No. 6S1).
If the intended vehicle width exceeds 2,100 mm and if the rear parking lamps are to be mounted by the attachment
manufacturer, it is only possible to order parking lamps that are to be mounted on the roof in front (PR-No. 6S3) (SBBR
lamps can be left out at PR-No. 8SZ; preparation SBBR lamp).
19
According to article §51a. of the German motor vehicle traffic regulations (STVZO), vehicles with a length of more than 6
m must be provided with yellow side marker lamps and lateral reflectors.
In the LT delivery program, only the chassis with long wheel base exceeds the pre-set vehicle length.
If required, all standard vehicles are to be provided with reflecting side marker lamps.
All chassis with long wheel base are prepared ex-works for side marker lamps (wiring harness). The attachment
manufacturer is responsible for installing side marker lamps.
20
According to article §54 of the German motor vehicle traffic regulations (STVZO), multitrack vehicles must be provided at
the long sides with additional flashing indicators to be mounted in the first third of the front section.
If the permitted total weight is more than 3.5 t, the light intensity of these flashing indicators must lie between 50 cd (min.)
and 200 cd (max.). All vehicles with a permitted total weight of less than 3.5 t are to be provided with small lateral flashing
indicators (5W). All vehicles with a total weight of more than 3.5 t are to be provided with large lateral
flashing indicators (21W).
Minimum visual angle ranges are pre-defined for mounting of lateral flashing indicators. As a result, it is mandatory to
mount various flashing indicators, depending on the attachment width: Small lateral flashing indicators
• Width up to 2,100 mm
Large lateral flashing indicators
• Width between 2,101 and 2,200 mm
Large lateral flashing indicators with adapter
• Width between 2,201 and 2,500 mm
Due to the confinements imposed by vehicle length (cf., item 3.13), permitted total weight and attachment width, the
required combinations of flashing indicators/marker lamps are already pre-defined for standard vehicles. Only attachment
widths of more than 2,200 mm require large lateral flashing indicators with adapter (can be ordered, PR-No. 8F8).
21
According to EU Directive 76/756 EEC and article §54 of the German motor vehicle traffic
regulations (STVZO), motor cars that are to be used in the Federal Republic of Germany must
be provided with mirrors. These mirrors must be designed and installed in such a way to permit
the driver to look backwards and sideways - also if a trailer is hooked up to the vehicle - so that
he or she is capable of observing the traffic.
As standard, all LT-model are equipped with an interior mirror and a exterior mirror - for a max.
attachment width of up to 2,150 mm.
For attachment widths between 2,150 mm and 2,400 mm, exterior bracket mirrors are available
(normal/large bow).
Availability of LT exterior mirrors
(see also Sales Manual):
• Standard mirror (serial) - attachment widths up to 2,150 mm
• Bracket exterior mirror, normal (standard dump truck and LT 46 chassis) - attachment
widths between 2,151 mm and 2,300 mm
• Bracket exterior mirror, large - attachment widths between 2,301 mm and 2.400 mm
22
The attachment manufacturer has to ensure that
• it is possible to mount the largest permissible tyre size,
• the distance between tyres and mudguard or wheel housing is sufficient, even with mounted snow chains or
antiskid protection chains and with full single-sided or two-sided compression. Consider the dimensions that are
specified in the chassis drawings.

According to EU Directive 70/221 EEC and article §32 b. of the German motor vehicle traffic
regulations (STVZO), motor cars at which the distance between rear limitation and rear axle is
more than 1,000 mm and which have, in unloaded condition, a headroom of more than 700
mm (applying either to the total width of the rear chassis or the main car-body parts) above
lane, must be provided with an underrun protection.
At all LT vehicles, the main car-body parts lie less than 700 mm above lane. For this reason,
standard vehicles require no underrun protection. As standard, all LT 46 chassis models
(with/without flatbed) are equipped with a rear underrun protection.
The maximum distance between the rear edge of the attachment and the main car-body parts
(at the chassis, this applies to the bulb retainers) is 400 mm. If 400 mm are exceeded, the
attachment manufacturer is obliged to construct and install an underrun protection
corresponding to the relevant EU Directives.
For this purpose, it is recommended to use the screw connections at the frame that are
provided for the trailer coupling.
25
According to EU Directive 89/297 EEC and article §32 c. of the German motor vehicle traffic
regulations (STVZO), motor cars whose permitted total weight exceeds 3.5 t and whose main
car-body parts have a headroom of more than 500 mm above lane, must be provided with
lateral protectors, if these vehicles are to be used in the Federal Republic of Germany.
Excluded from this regulation are tractive units, driven machines and special vehicles whose
operational purpose cannot be fulfilled by the lateral protectors.
As standard, all LT 46 flatbed models are provided with lateral protectors. At the LT chassis
(cab/double cab without flatbed), no lateral protectors are mounted. The lateral protectors must
be constructed and installed by the attachment manufacturer relating to the attachments
according to the relevant EU directive.
If lateral protectors are to be installed subsequently, the following instructions apply:
• Component parts, such as battery box, air receivers, petrol tanks, lamps, reflectors,
spare wheels and tool boxes, may be installed if the prescribed distance dimensions
are kept. Brake, air or hydraulic lines and other parts must not be attached to the
lateral protector.
• Function and accessibility of all equipment, modules, units, etc. of the vehicle must
not be impaired.
26
There are clear instructions available for handling vehicles with longer service lives (see manual Service Technology,
volume: Inspection and Maintenance, item 3.2.4, Storage of Brand-New Vehicles). These instructions are defined by the
customer service and are to be adhered to. Observe the following note when handling the tachograph: If the acceptance
stamp is older than six months, the tachograph should be re-submitted to an acceptance test.
27
General information
• The attachment of the trailer coupling must correspond to the specific directives of the relevant country. In the
Federal Republic of Germany, standard DIN 74 050 has to be complied with.
• Consider free-space dimensions*. In the Federal Republic of Germany, standard DIN 74.058 has to be complied
with.
• If deviations from the German regulations for the prevention of industrial accidents (UVV) are necessary, it is
required in the Federal Republic of Germany to request an import certificate ["Unbedenklichkeitsbescheinigung"]
from: Berufsgenossenschaft für Fahrzeughaltung [German Trade Co-operative Association for Matters
Associated with Car Owning], 22757 Hamburg (phone +49 [0] 40/38 10 91).
• If trailer couplings are to be installed subsequently, only products which have been approved by us and original
Volkswagen end cross-members may be used. Attachment points are available at our end cross-member and/or
side rail.
• The size of the trailer coupling is defined according to the D-value.
The size of the trailer coupling is defined according to the D-value
D = control-shaft value
mk = permitted total weight of the tractor (motor car) in t
mA = permitted total weight of the trailer in t
g = 9,80665 m/s2
The permitted trailing load can be taken from the valid sales documents or the guide "Trailer
Operation". In order to permit the trailers being exchanged in transborder traffic, the distance
dimension, x, must not exceed 300 mm.
* If the trailer is extremely low lying or if a special attachment is extremely overhanging, it may
be prohibited to use a trailer coupling.
Mouth clutch (can be ordered ex works under PR-No.1D5)
• Max. distance between the middle of clutch bolt of the trailer coupling and attachment
end: 420 mm. Keep clearances.
• In special cases, it is permitted to exceed the distance dimension of 420 mm: Max.
distance 650 mm for vehicles with tiltable attachments or rear attachments. Max.
distance 1,320 mm, if the headroom between lane and the lower attachment edge is
at 1,150 mm. A suitable remote control for the clutch must be available. The safe
actuation of the clutch must not be impaired.
28
Spherical coupler (can be ordered ex works under PR-No.1D1)
• Keep clearances.
• The installation is only permitted at approved trailing supports.
• It is not permitted to perform the installation only at the underrun protection. Modifications of the underrun
protection must be arranged with the responsible testing and research laboratory (in Germany: TÜV).
29
An operating permit is available for the brake system of the vehicles. This licensing becomes invalid if the brake system is
modified. Therefore, modifications of the brake system are illegal.
If it cannot be avoided to perform works on the brake system, e. g. changing the wheel base, the following instructions are
to be considered:
• Replace hydraulic brake lines completely.
• Dimensions of roller laminated tube: 4.75 x 0.7; plastic lines/tubes are not permitted.
• Mould lines only with a bending fixture
• Bend radius = 17.5 mm
• Clean the interior of lines.
• Keep safety clearance to heat sources, pointed, sharp or moving parts
• Attachment with plastic loops, max. distance 500 mm
• Let the ALB controller be re-adjusted by a VW dealer if the weight has changed.
After finishing works, check whether the brake system is perfectly functioning.

• If a retarder is to be subsequently installed at the transmission or in the drive-shaft strand, it is required to ask the
responsible department for a permission. Approvals are not generally given but are basically limited to specific
vehicle designs and wheel bases.
The mounting drawings must include the following information:
• Position of the retarder in the vehicle
• Drive-shaft angle
• Length of the drive shafts
• Due to the additional weight of the retarder, the distribution of weight and adherence of the permitted axle loads
has to be checked. Check location of the centre of mass of the attachment. Adjust it, if required.
• Mounting is only permitted at vehicles with sufficiently dimensioned electrical installation (generators and
batteries with sufficient capacity). Ensure a sufficient ground connection of the retarder.
• Ensure sufficient freedom of operation.
• In the drive-shaft strand, attach the retarder only at the bar of the chassis frame using brackets with silent blocks.
• Protect lines against heat by using an appropriate insulation. The permitted maximum temperature for polyamide
lines is 80°C.

• The design of the auxiliary drive and the selection of the gear ratio depend on the power and speed (revolutions
per minute) of the modules to be actuated.
• Transmission-dependent auxiliary drives may only be switched on/off with the vehicle standing still.
• Information on max. transmissible torques (Nm) of the individual auxiliary drives can be taken as guide values for
shock-free and non-oscillating operation. According to DIN 922, the above specifications are based on a
fatigue-limited gearing layout and a calculated service life of 500 hours. Additionally occurring inertia forces at the
modules to be actuated are not considered.
• The gear ratio of the auxiliary drive has to be selected in such a way, that the minimum speed (engine), i. e.
between 1,000 rpm and 1,200 rpm, is not exceeded if the auxiliary drive is loaded. The output decrease should
lie within the range of the maximum engine torque.
• Exposed drive shafts, fan rotors or belt pulleys must be covered.
• It is not permitted to attach belts or chain drives to the drive shaft or flange of the auxiliary drive. However, if
exceptions from the above specifications cannot be avoided, the appropriate drawings and data must be
submitted for approval.

Usually the flatbed must be raised according to the required subframe height. Since the standard flatbed version affected
here is provided with very high, u-shaped cross-members, it is possible to perform the following procedure:
The cross-members of the standard flatbed are cut out in the areas the chassis side-rails in such a way, that it is possible
to fit in precisely the continuous subframes and to connect them to the cross-members by means of welding. (Position of
subframes exactly above the standard side rails, see illustration below.) Dimensions of subframes and attachment of the
loading tailboard to be performed according to our construction guideline.
The attachment of the standard flatbed, which is modified as described, can be performed without changing the chassis,
however, appropriately longer screws are to be used. The spacing between flatbed cross-member and chassis brackets is
to be levelled out with shims (bushings).
34
General Information:
• For a perfect connection between chassis and attachment, for all attachments a subframe or a floor panel
assembly (taking over the function of the subframe) is required (except for self-supporting attachments and
subframes as a base group).
• The subframe side rails should lie flatly and following the chassis profile on the upper belts of the chassis frame.
• The following applies to LT 46 models (twin tyres):
In the area of the rear axle, the chassis-frame side rails are inwardly offset. The subframe side rails need not
follow this offset but can be executed continuously straight. Wooden fillets between chassis-frame side rail and
subframe side rail are not permitted. A bracket attachment, via subframe cross members, is required in the area
of the rear axle.
• Subframe cross members are to be arranged above the chassis-frame cross members.
• For the side rails, use bevelled u-beams or standard u-beams that are generally used for the construction of
vehicles (no rolled steel sections). Box sections are also permitted.
• The side rails dimensions result from the moment of resistance (Wx) required for attachment and chassis. See
diagram 3.3.2. The specified moments of resistance and section/beam dimensions refer to frame side rails that
are evenly loaded on both sides.
If several attachments are to be assembled on a chassis (e. g. flatbed and loading tailboard), the greater value of the
specified moments of resistance must be taken as a basis for defining the subframe.
Subframe as base group:
A subframe with continuously running side rails is not required if the base group of the attachment can take over the
function of the subframe.
Subframe for reinforcing the side bars in the front-end area of the vehicle: For example, when lifting platforms are
operated, the entire vehicle may be lifted by 4 hydraulic supports, so that the wheels no longer touch the ground. Due to
the high weight of the front end of the vehicle, inadmissibly high tensions appear in the chassis side rails in the area of the
front support. For this reason, it is mandatory to reinforce the chassis frame if this application is planned. This requires to
35
lead the subframe through the back of the cab to a location under the seat box. It has to be attached with a supplementary
bracket and a bolted connection. An execution recommendation can be requested at Volkswagen AG, department NV-VS.
This subframe execution does not permit to install an additional battery (PR-Nr.8FR).
Material Qualities for Prescribed Steel Subframes:
The subframe with bracket attachment (force-locking) is to be implemented as St 12.03 or St 37-2.

Subframes that are made of high-strength steel must at least correspond to the stiffness of
steel subframes. The attachment must be realised with force-locking capability.
Flatbed truck attachments, aluminium type
• Adhere to the instructions of the aluminium manufacturers
• Side rails, plank floor, floor mats and carrying hook conveyors must form a
self-supporting unit.
The profile transition at the front ends of the side rails should be gradually realised.

If it is required to implement very high side rails or if low total heights of the chassis are to be implemented, the
u-beam - at locked-force connections - must meet the following specifications:
• It must be closed as a box
• It must be nested into each other
• It must be nested
As a result, the moment of resistance and the torsional stiffness are increased. Make sure that the transition between
closed side rail and open u-beam is properly executed.
Profile dimensions
The profile dimensions for subframe side rails (open profile), subframes and chassis frames should approximately have
the same material thickness and flange width.
Profile height (in mm)
37
Determine the mounting method depending on the chassis type, attachment and according to the operation purpose of the
vehicle. Attach the subframe on the fixing brackets (which are available as standard) of the chassis frame. Use shackle
attachments if additional attachment points are required. Define the number of attachments in such a way that is it
ensured that the braking and lateral forces are properly absorbed.
The correct attachment is decisive for:
• Road behaviour and the operational safety of the vehicle.
• Operational life of chassis frame and attachment.
If locked-force connection are used, the side rails must be attached length and crosswise.
If pre-assembled subframes are used, constructional tolerances of the chassis frame width (max. + 6/-3 mm) are to be
considered. Compensate for manufacturing related frame bending (max. 6 mm) by using supports.
Bracket attachment with side rail

Locked-force connection, bracket attachment
• A movement of the subframe side rail in relation to the chassis side rail is possible with restrictions.
• Perform rigidity strength calculations for each individual side rail.
• Divide up the bending moment according to the moments of inertia.

The mounting frame is exclusively used for directly receiving attachments. Only screws are permitted for attaching the
mounting frame at the chassis frame. The mounting frame needs not to cover the entire chassis frame up to the cab - as is
the case with the subframe. (see item 3.3.3. Figure: Bracket attachment with cross-member mounting frame)
The mounting frames does not meet any strength requirements to protect the vehicle chassis.
40
When the modified vehicle is brought forward to an inspection or acceptance test, according to EC directive, Brakes,
71/320/EEC, the centre-of-mass height must be mathematically proved using a loaded vehicle. Bases of calculation and
permitted centre-of-mass heights can be requested from Volkswagen AG.
If the centre of mass lies high, provide stabilizer bars and reinforced shock absorbers (if available). If the centre-of-mass
height exceeds 960 mm at the LT28 / LT35, it is required to use the stabilizer bar at the back (OBC) and reinforced shock
absorbers. Permitted centre-of-mass height: 1050 mm. If the centre-of-mass height exceeds 1,100 mm at the LT 46, it is
required to use the reinforced stabilizer bar at the back (OBD).
Centre-of-mass heights - base vehicle: (empty, including driver with 75kg)
LT 35 Chassis:
h = 780 mm
LT 35 Box-type delivery van: h = 840 mm
LT 35 Station wagon:
h = 850 mm
LT 35 Flatbed:
h = 805 mm
LT 46 Chassis:
h = 725 mm
Volkswagen AG does not provide information on the road/braking/steering behaviour of attachments used for loads with
an unfavourable centre-of-mass position (e. g. rear, high and side loads). The attachment manufacturer is responsible that
these attachments do not impede the road-holding qualities of the vehicle.
41
Driver s cab:
Functioning, smoothness and free movement of instruments and operating equipment as well as the stability of supporting
parts must not be impaired by modifications performed at the cab. If the cab is to be built over, the permitted
centre-of-mass position and the permitted front-axle load is to be considered.
Roof loads/roof racks:
Box-type delivery vans and station wagons:
• Max. 300 kg (vehicles with high roof: 150 kg) if the load is uniformly distributed over the entire roof surface.
• A stabilizer bar must be installed at the front axle.
• The roof rack must have at least 5 sustainers (with a roof of 300 kg) or 4 sustainers (with a roof of 150 kg). The
sustainers are to be evenly positioned.
• If the roof rack is shorter, the loading has to be reduced proportionally.
Vehicles with cab or double cab:
• Max. 100 kg if the load is uniformly distributed over the entire roof surface.
Note: The installation instructions only apply to box-type delivery vans and station wagons.

• The connection between bows and side walls must be laid out in such a way that a locked-force connection is
ensured (flex-resistant connection of bow and roof chassis). The new roof structure must correspond to the
standard roof relating to stiffness. The required minimum moment of inertia (Ix) of the roof bows can be taken
from the following table.
• Roof height Moment of inertia (Ix), per bow 250 mm 40.000 mm4 400 mm 65.000 mm4 550 mm 86.000 mm4

• In case of deviations, it is required to ask the responsible department for a permission.
Notes:
• Plastic roofs are only suitable to a limited extent for mounting roof lamps.
• The roof load is limited.
Rising roof
• If a rising roof is to be mounted, at least two thirds of the original roof surface must be maintained.
• Do not remove any cross-beams or supporting parts.
Air baffles: Air baffles on the cab roof may only be attached with retainers at the door frame or at the rear welding flange
(back wall of roof). Bores in the cab roof are not permitted for attaching components. If other roof attachments (e.g.
air-conditioning system) are to be installed, it is required to ask for the permission of Volkswagen AG.
43
At self-supporting attachments, a subframe with appropriate side rails is not necessary, if the cross members keep a
maximum distance of 600 mm. This distance may be exceeded in the rear-axle area.
Self-supporting attachments are to be attached at the chassis over all available brackets (2 screws per bracket).
44
• The forces which are induced punctiformly are to be distributed uniformly via a subframe over the entire chassis
frame.
• For this purpose, the subframe should lie without torsions over the side rails and should be guided up to the cab
(procedures according to item 3.3).
• At a chassis with double cab it may be necessary to shorten the rear chassis overhang. This measure is to be
controlled on the basis of axle-load calculations.
• High centres of mass for attachments and net-loads impair the driving and braking behaviour. The chassis can
be provided ex-works with stabilizer bars/attenuation.
• Due to the width and length of the attachment, it may be necessary to modify lighting, markings and exterior
mirror. These modifications are listed under items 3.12 - 3.15.
• The necessary underrun protection and lateral protection is described in items 3.18 and 3.19.

• When handling trilateral and rear dumping attachments, arrange the spherically seated bearings at the rear end,
close to the rear axle.
• Provide guide angles for the relevant spherically seated bearings, so that the dumping bridge is guided during the
dumping.
• The maximum inclination angles and dumping bridge lengths can be taken from the axle load calculation,
considering the maximum external attachment lengths.
• The pressing support is to be attached on cross members in the subframe.
• It is recommended to arrange the subframe cross-members over the cross members of the chassis frame.
• At trilateral dumping attachments, the point of application force of the dumping press is to be set in front of the
centre of mass of attachment and net weight.
• Protection If required, the dumping bridge has to be secured against dropping. Take measures against
unintentional operation. As a visual warning (dumping bridge not in driving position), a control lamp is to be
connected in the cab.
• Subframe
The subframe must be must be continuously designed and be provided with sufficiently dimensioned cross
members made of steel. Close the rear area adjacent the box and brace it with diagonal cross. Connect the
subframe with the chassis frame corresponding to the load, according to item 3.3.3.
• To fix the subframe laterally, weld guide plates in the area of the cross members at the subframe.

General information
It is not permitted to modify spring characteristics, brake system and steering unit. Exceptions must be approved by
Volkswagen AG before the modification is carried out.
Note:
Changing the steering and braking forces for vehicle conversions for disabled persons is not possible.
Airbag
If the attachment manufacturers modify the structure of the vehicle, e. g.
• modifications of the front section of the vehicle
• mounting of belt retractors if the B-pillars are left out
• modifications of the floor structure in the area of the airbag trip device
• modifications of the seats, resulting in altered kinematics of the passengers
• modifications of the airbag-system cabling
• modifications of the system design
the safe functioning of airbag and belt retractor can no longer be guaranteed. These component parts may only be used
after having been approved by Volkswagen AG.
Emission behaviour (exhaust gas/noise)
If parts are to be modified that are producing exhaust gas and noise (e. g. engine/injection pump/control unit, exhaust
system/catalytic converter, air suction installation, tyres, etc.), it is required to perform exhaust gas and noise
measurements. It is also necessary to adhere to the current versions of the specific national directives and regulations.
For this reason, parts which are installed as standard to reduce emissions should not be removed or changed. Otherwise
the license may expire.

is our supplier of serial seats for the passenger compartment. This firm is also offering two seat variants which can be
positioned against the driving direction without changing the standard seat mounting points in the 1st row of seats. This
applies to the narrow triple seat and the double seat. Since we do not supply these seat variants, it is only possible to
order them directly from this manufacturer. These seats are already provided with (automatic) lap belts. The pre-cut fabric
covering material reference allows for the omission of the three-point belts!
Prices: State 21 November, 1997:
• Narrow triple seat based on standard seat, with upper part turned by 180° and with the seat mating-part sets,
including the installation materials for the vehicle floor, excluding head restraints. DEM 1292/piece (without
turnover tax)
• Double seat, as above, DEM 968/piece (without turnover tax)
The prices are ex-works from Lohr am Main, Germany, excluding packaging.
The head restraints can be ordered as replacement parts from Volkswagen using Part No. 2D0 881 901... The nav_side
missing here depends on the selected seat cover.
Note:
Since the floor attachment for the above mentioned seat variants are taken over from the standard seat variants without
modifications, it is possible to replace the above mentioned seat variants by the corresponding standard seat variants, if
the backrest locking at the side panel, which is required for this, was appropriately retrofitted according to the series
specifications.
48
At the multi-purpose/box-type delivery van, attachment and base group form a self-supporting unit. Supporting parts of this
self-supporting unit must not be removed without being replaced by another component. Baffles have no supporting
function. Modifications, even the complete removal, are permitted. If car-body parts are to be modified or to be installed, it
is only permitted to weld if bonding is not possible.
• Cut-outs in the side wall
If profiles are cut in order to install cut-outs (windows, doors, bonnets, ventilation, air exhaust, etc.), the cut-outs
must be reinforced by an enclosing frame and must be welded to the cut profiles.
• Roof heightening (plastic roof)
refer to item 3.6, Roof design
At closed bodies with partition walls ventilation slots are located in the partition wall and the D-pillars. At car modifications
it is only allowed to cover these ventilation slots, if new slots are produced in the cab instead. For example in the cab
doors.
49
If the wheel base is to be modified or if the overhang is to be extended, the material quality and dimensions of the
lengthening piece must correspond to the chassis frame (St 12.03). Functioning, smoothness and free movement of
instruments and operating equipment as well as the stability of supporting parts must not be impaired by the performed
modifications.
Cut-outs in the backwall of the driver™s cab must be provided with an enclosing frame. The remaining diagonal struts and
cross-beams are to be reinforced by junction plates and are to be welded to the inserted frame.
The distance between cab and attachment must be at least 50 mm.
Frame modifications
• The permitted axle loads must not be exceeded. It is also required not to fall below the permitted minimum front
axle load.
• Attach the underrun protection as explained for standard vehicles.
• Extend the subframe up to the frame end.
• Check the function of the towing device.
• Reinforcements must be available for desired towing device.
The side rails are hollow profiles (cap profiles). If it is required to drill, the appropriate operations may only be performed in
the specified areas.
It is not permitted to drill:
• At the upper and lower belt of the chassis frame. Exceptions are boreholes at the rear frame end. However,
these boreholes must not lie in the area that are reserved for the supporting functions of the rear axle. In addition,
they must not be applied to parts that are attached to the frame.
• In the range of profile modifications of the frame side-rails (frame drop and frame indent).
• At force-application points (e.g. directly at the spring brackets).
In special cases, it is permitted to drill boreholes in the crosspiece of the frame side rails.
• Distance a: at least 20% of the frame height
• Hole separation b: at least 50 mm
• max. bore diameter: 15 mm
Grind and ream after drilling. Before usage, distance bushes must be welded in.
50
According to item 2.3, the permitted maximum rear overhangs (depending on wheel base and permitted total
weight) are to be kept.
For this purpose, consider the following instructions:
• If the frame is to be extended by more than 350 mm, an additional cross member is to be installed.
• It is required to check the permitted trailing load (according to the vehicle registration document). Reduce,
if necessary.
• Overhang extension according to the illustration.
As an ex-works preparation, the SBBR line can be installed with a spare section of 700 mm. Ordering options can
be taken from the sales documents.

Perform wheel-base extensions of the longest standard base. If the wheel base is to be modified, the next larger standard
wheel-base is to be used and shortened. Reinforce the intersecting point with sheet-metal shoes.
Wheel-base modifications based on displacing the rear axle are not permitted.
Separation points are not permitted in the area of:
• Force-application points
• Axle guiding and axle spring-suspension
• Profile modifications
After the wheel base modification, the chassis has to be reinforced by a continuous subframe.
Moments of resistance required for the subframe:
• Up to the max. standard wheel-base: 30 cm3.
• Above the max. standard wheel-base: 15% increase.
The wheel-base modification results in an altered turning circle and changed weight values.
Wheel base modifications lying within the range of the minimum/maximum standard wheel-base, require no special
permission.
Drive shafts
• If wheel-base modifications are to be performed, the drive-shaft arrangement and length must correspond to that
of a comparable standard vehicle.
• The diameter and wall-thickness of the drive-shaft must correspond to that of the standard vehicle.
• If required, use several drive shafts with intermediate bearings.
• The inflection angles (ß1 = ß2) must not exceed 6° . Deviations impair operating life and noise
level.
• Counterbalance drive shafts before mounting them.

General information
When performing welding operations with electrical welding sets, adhere to the following instructions:
• Welding works at the chassis frame may only be performed by trained and sufficiently qualified staff.
• Remove and cover the positive and negative terminals of the batteries.
• Connect earth terminal of the welding set directly to the part to be welded. Caution! The earth terminal of the
welding set must not be connected to any other module (engine, transmission, axles, etc.).
• Do neither touch the housings of electronic modules (e. g. control units) nor electrical lines with the welding
electrode or with the earth terminal of the welding set.
• At cabs which are independently supported, connect the earth terminal of the welding set to the cab.
• Before beginning the welding work, it is required to protect the springs against weld splatters. Do not touch
springs with the welding electrodes or the electrode holder.
Caution!

• At the chassis frame (except for wheel base and frame modifications)
Welding at the vehicle frame
At the upper and lower belt of the chassis frame, it is not permitted to weld (except for wheel-base modifications and frame
extension).
Connect the earth terminal of the welding set directly to the vehicle part to be welded.
• Only use well drained electrodes with lime-basic coating. Electrode diameter 2.5 mm.
• Current intensity per mm of the electrode diameter is max. 40 A.
• The electrodes may only be welded together with direct current via the positive pole. In general, the welding has
to be performed from bottom to top.
• Inert gas shielded arc welding is permitted.
• Weld filler rod size between 1 and 1.2 mm.
• The weld material must at least have the same yield point and tensile strength like the material to be welded.

• At backfitting of a heat exchanger, it is important the bleed the cooling water system completely:
heater output:8,7 kW
air-mass flow: 360 kg / h
volume flow: 1500 l / h
the additonal heat exchanger from the T4-selection can be recommended.

General information
• Do not loosen or remove the terminal clamps of the batteries with the engine running.
• Only tow-start vehicle with connected batteries.
• Charge batteries only then with a quick-charger, with the batteries being disconnected from the vehicle circuit.
Positive and negative terminals must be removed. Adhere to the operating instructions!
• Installation of additional electrical consumers.
• Coat cables which are to be routed near exhaust systems with fire-proof material.
• Route cables in such a way that abrasion marks can be avoided.
Electromagnetic compatibility (EMC)
In motor vehicle power-supply circuits, the individual consuming devices cause electrical disturbance variables.
Volkswagen AG checks whether electronic components (which are installed by the manufacturer) are electromagnetically
compatible inside the vehicle.
If electrical or electronic systems are to be upgraded or retrofitted, it is also required to check their electromagnetic
compatibility.
The following standards supply relevant information:
• DIN 40839
• DIN 57879, Part 3
• VDE 0879, Part 3
• VWTL 965
• VWTL 82066
• VWTL 82166
• VWTL 82366
In addition, it is required to consider the EMC Directive 72/245 EC, version 95/54 EC.
More information can be requested from the responsible department.
Supplementary current-collecting consuming devices
Adhere to the following instructions if additional electrical consuming devices are to be installed later on:
• On special request, provide available batteries and generator with higher output.
• Connect no further consuming devices to fuses which are already assigned.
• Connect no additional lines (e. g. with insulation piercing connecting devices) to available lines.
• Protect consumers with additional fuses sufficiently against short circuits.
Subsequent installation of an additional battery
An additional battery may only be installed in connection with a D+ relay. This battery may only be assigned to additional
consuming devices, such as auxiliary heater, loading tailboard or electrical devices to be used in mobile homes
(refrigerator, etc.). If the additional battery is to be placed in the passenger compartment, the ventilation has to be realised
using a central degassing tube leading outside.
58
Electrical lines
Adhere to the following instructions if electrical lines are to be extended:
• Use only FLKR lines with the same cross section and colour as the standard lines.
• The lines must be coated with an insulating hose (GGVS vehicles with a corrugated hose).
• Attach only original Volkswagen plug connectors to the line ends.
• The connection of electrical lines may only be realised via tapping boxes.
• Cables of the anti-lock brake system may only be extended with original Volkswagen cable-sets.
59
In the event of tampering with the structure of the vehicle by the body manufacturer for example.
• Modifying the front end
• Attaching belt tensioners with no B-pillar,
• Modifications to the floor structure in the area of the airbag trigger control unit,
• Modifications to the seats and thus to the kinematics of the occupants,
• Modifications to the wiring of the airbag system,
• Modifications to the system design (e.g. installation location of the sensors,
• Installation of parts in the vicinity of the outlets or inflation range (only tested retrofit solutions permissible),
reliable operation of the airbag, passengerairbag and belt tensioners can no longer be guaranteed. These components
should therefore only be used with the approval of the responsible department.

1) Station wagon
a) If the passenger compartment is being ordered without standard seats, the station wagon will then generally be
provided ex works with 3 prepared mounting points for the first two rows of seats, including the single-sided
preparation for connecting the backrests of the standard seats at the contacting side wall with double and narrow triple
seat, respectively, at the wide triple seat, the two-sided connecting preparation.
Exception: Station wagons with 2 sliding doors. This variant is not provided with a prepared floor mounting points for the
first row of seats. For this reason, it is not possible to retrofit standard seats in this case.
(Note: Seats are also not available as standard!).
b) It is required to order the prepared floor mounting points for the 3rd row of seats, including the two-sided
connection preparation for the backrest of the wide triple seat bench at both side panels, with PR.-No. 3WE since they
are not available for the basic version.
Note: A retrofitting of the floor mounting points, including the both-sided connection preparation for the backrest of the
wide triple seat, in the 3rd row of seats is not possible.
c) However, if a double seat is ordered ex works for the 1st and / or 2nd row of seats, the 3rd floor mounting point
(which is not required) for the affected row(s) of seats will not be appropriately prepared. A subsequent upgrade to a
triple seat is possible (in front only onto a narrow triple seat), but is, however, extremely complicated! If an upgrade to a
wide triple seat (only for the 2nd row of seats) is to be realised, the connection preparation for the backrest on the
previous passage side of the double seat also has to be retrofitted.
d) For conventional single seats mounted in driving direction (not available ex works; to be supplied by the attachment
manufacturers) on the vehicle floor of the passenger compartment of the station wagon and/or the boot space of the
box-type delivery van, on the left and right of the side panels, a suggested solution for retrofitting the belt anchorage points
of three-point belts (to the left and right of the single seats on the vehicle floor and at the corresponding side panels) was
developed and tested by TÜV Rheinland [Testing and Research Laboratory of the Rhineland] in a sprinter. Since the
affected car-body areas are identical with that of the LT, the expert assessment No. 55110226-00, dated 19/10/1995, can
also be applied to the Volkswagen LT (LT 2). The attachment of the single seats on the vehicle floor are not dealt with.
The expert assessment is available on request (Fax 49-511-7983895).
2) Box-type delivery van
a) The boot space floor is not prepared to be equipped with station wagon standard seats. It is not possible to retrofit the
floor mounting points!
Note: A seat package is available ex works for all box-type delivery van versions with a narrow triple seat for the 1st row of
seats!
b) Retrofitting of single seats performed by attachment manufacturers: See station wagon, item 1d).
