be possible to raise the hood an inch or
so until held by a spring-loaded safety
catch. lnsert the fingers and push back
this safety catch, when the hood may be
lifted right up. The hood is held open
by a stay clipped to its underside, and a
small locating cup is provided in the
radiator top tank to keep the stay secure
when in use.
The spring-loaded safety catch is
designed to hold down the hood while
driving in the event of the hood not
having been properly locked. When
closing the hood a slight pressure
exerted downwards on the hood top
will help the locking catch t o engage
positively.
Hood Catch (Commercial Vehicles):
T o open the hood pull the control knob
situated below the fascia panel, on the
extreme right-hand side. The hood will
rise an inch or so and will then be held by
a spring-loaded safety catch, after which
the procedure is exactly the same as that
given for the Sedan.
In the case of the 'A40 Sports Modrl
the hood is held open by a sliding stay
which is bolted from the underside of the
hood to the bulkhead.

BREAKING-IN THE NEW VEHlCLE
T H E Austin 'A40' is designed and built with great care to high quality standards.
For that reason the owner will find that considerate treatment during the all-important
breaking-in period will be well repaid by trouble free running and the utmost in performance throughout its life.
The following speeds should not be
ewceeded in the gears for the first 500
miles.

lt is most important to remember that
at no time during the breaking-in period
must the engine be over-loaded, as iri
attempting to ascend grades in high gear
at low vehicle speed. The load should be
eased by shifting down to a lower
gear.
Fierce acceleration must also be
avoided, and remember that the engine
should never be raced in neutral.
On completion of the first 500 miles
the breaking-in speed in each gear
may be progressively increased, but full
power should not be used until at least
1,500 miles have been covered, and even
then only for short periods at a time.
N o engine or complete vehicle can be
considered fully broken-in until it
achieves 2-3,000 miles.
The use of upper cylinder lubricant is
recommended at al1 times, but most
particularly during the breaking-in
period. See centre pages for recommended brands.

are extremely dangerous.
REGULAR ATTENTIONS
T H E following is a convenient list of regular attentions which the vehicle should
receive to keep it in good mechanical condition. These instructions should be closely
followed whether the attentions are performed by the owner or the local garage.
The attentions under the Weekly headings are based on the asssumption that the
maximum mileage per week does not exceed 500.
Under more arduous conditions, such as very dusty or very muddy roads, long
distances at high speeds or with heavy loads, it will be advisable to attend to chassis
lubrication more frequently.
Every time gasoline is put into the tank, the engine oil level and the radiator water
level should both be checked. Top up if necessary.
EVERY 500 MILES OR
WEEKLY
Shackle Pins : These are on the rear
ends of the rear road springs and should
be given a charge of oil once a week.
There are two nipples, one on each top
shackle.
Front Suspension: Apply the oil gun to
the lower arm joints where they meet the
knuckle pin housing ( C ) .
Knuckle Pins: Apply the oil gun to the
two nipples on each knuckle pin. This
is best done when the vehicle is partly
jacked up, since the oil is then able to
penetrate to the thrust side of the
bushings (G and D).
In the case of Commercial Vehicles,
which are supplied with a screw type
lifting jack, the load on the front suspension should be relieved by placing the jack
under the lowest point of the frame front
cross member, with the lipped end of the
lifting platform firmly against the fonvard
side, and then partly raking the vehicle.
Steering Connections: Apply the oil
gun to the steering center tie rod nipples
(2) (A) and the steering side cross tube
nipples (4) (E and F) and top up the
steering idler (B) via the oil plug orifice.
N.B.-On
no account should the
steering idler be overlooked, as lack of
lubricant in this component may cause a
serious breakdown due to the additional
load imposed on the steering box.
Brakes and Controls: With the oil can,
oil al1 the handbrake linkage points,
brake and clutch pedal linkages and
carburetor control joints. Also oil al1
the gear shift control joints.
500 MILES
Engine: On new and reconditioned
engines the pan should be drained and
refilled with new oil after the first 500
miles. At the same time as these changes
are made, the cylinder head nuts should
be tested and tightened if found necessary.
Transmission and Rear Axle: After 500
miles on new vehicles, drain and refill
the transmission and rear axle.
Always drain the oil after a run, since
it will then flow more easily.

Engine: Drain the pan and refill with
new oil. Capacity is 8.4 pints (7 Imp.).
Transmission: Check the level and top
up if necessary. For access lift the floor
carpet and remove the rubber plug o n
the right side of the transmission covering. The filler plug is then accessible.
Remove the plug and fill up to the
bottom of the threads. This gives the
correct level.
Clutch Pedal: With the oil gun, lubricate the nipple at the base of the lever.
Brakes: Apply the oil gun to the
brake balance lever on the rear axle, the
handbrake pivot, and the brake pedal
pivot nipple.
Rear Axle : Check the level and replenish if necessary. The correct oil
should b r used and injected into,the axle
casing from underneath, using the
adapter o n the oil gun.
First remove the plug, which is o n the
right lower front side of the axle, then
place the end of the adapter into the oil
hole, and inject the oil.
The plug also serves as an oil level
indicator. Therefore, d o not replace the
plug at once, but give time for the superfluous oil to run out if too much has
been injected. This is most important,
because, if the rear axle is overfilled the
lubricant may leak through to the brakes
and render them ineffective. Wipe away
the excess oil frorn the casing.
EVERY 3,000 MILES
Distributor Cam- and Drive-Shaft Bearings: Lubricate the distributor cam-shaft
bearings by withdrawing the molded
rotating arm from the top of the distributor spindle and carefully adding a
few drops of oil round the screw exposed
to view. See page 25 for recommended
oils. Take care to refit the arm correctly
by pushing it on to the shaft and turning
until the key is properly located.

Wheels and Tires: Tighten the wheel
nuts and check the tire pressures, including the spare, using a tire gauge and
inflate if necessary. See that al1 valves are
fitted with valve caps. Ensure that there is
no oil or grease on the tire, since these
substances are harmful t o rubber. See
section of 'Tires' for correct pressures.

Check that the electrolyte in the cells
is just leve1 with the tops of the separators.
If necessary add a few drops of distilled
water.
Never leave the battery in a discharged
condition. l f the vehicle is to be out of
use for any length of time, have the
battery removed and charged about once
every two weeks.
Brake Supply Tank: Inspect and refill
to the correct level, which is one inch
from the top of the container. Use only
the recomrnended fluid.
Shock Absorbers: Ensure that there are
no visible signs of leakage and that the
rubber bushes are undarnaged.
EVERY 3,000 MILES
Spark Plugs: Rernove the plugs and
clean off al1 carbon deposit from the
electrodes, insulators, and plug threads
with a stiff brush dipped in kerosene.
Alternatively the plugs rnay be taken to
the local dealer for cleaning in a machine.
Clean and dress the plug points and
reset to the correct gap of ,018 in.
Before replacing the plugs check that
the copper washers are in a sound condition. Never overtighten a plug but
ensure that a good joint is rnade between
the plug body, the copper washer, and
the cylinder head.
Use only Charnpion N.8.B Long
Reach plugs.
EVERY 5,000 MILES
Air Filter: As well as acting as an air
intake silencer and filter, by a coupling
to the rocker cover, it also acts as a funie
extractor.
The wire mesh of the filter should be
cleaned out, and the oil changed. Wash
the mesh in gasoline, but d o not replace
until thoroughly dry. The oil level is
indicated by an arrow pointing t o a
srnall shoulder in the metal container.
Fue1 System: Check the flow of fue1 at
the carburetor inlet union, and if necesary clean the filter.
First remove the carburetor inlet
union and operate the pump hand
priming lever. Each pumping stroke
should force a strong jet of gasoline
from the union.
If the flow of fue1 from the pump is
restricted, remove the pump top cover
and lift out the filter over the pump top
chambers. Remove the drain plug and
clean out al1 sediment from the pump
chamber. Clean the pump filter and carefully replace. When refitting the pump
top cover ensure that the cork washer is in
good condition. A poor washer will not
permit an air-tight joint and the operation
of the pump will be impaired.
Remove the bowl of the carburetor for
cleaning, by taking out the two hexagonheaded retaining bolts. On turning the
bowl over the float will drop out and

Never use wire o r attempt to reamer when
clearing a jet. Eefore replacing the jets
ensure that the fiber washers under them
are in position. Replace the float the
correct way up as marked.
Speedometer Drive : Disconnect the
cable from the speedometer end and pul1
the inner member out of the casing. This
should be lubricated sparingly by smearing it with light grease. Jt is important
that the drive is NOT over-lubricated.
otherwise damage will be caused to the
speedometer head should the lubricant
find its way into the head.
T o re-assemble, thread the cable with
a twisting movement into the casing, since
this will help the cable to engage easily

Front Shock Absorbers: Check the fluid
levels and top up, if necessary. The
correct level is just below the filler plug
threads. See page 25 for recornrnended
fluids. Carefully clear away al! road dirt
and grit frorn the vicinity of the filler
plug before rernoval.
I t should be noted, however, that in
the case of the 'A40' Sports, it is necessary to rernove the shock absorbers frorn
the chassis before topping up.
Mount the shock absorber on to a steel
plate held in a vise and whilst working
the lever arrn both ways through its full
stroke top up with therecornrnendedfluid
until overflowing.
Rear Shock Absorbers: Check the fluid
levels and top up, if necessary. The correct
level is at the bottorn of the filleropening.
Decarbonising, Valve Grinding and
Tappet Adjustment: This attention may
not be needed so frequently on vehicles
used for long journeys. As a general
guide, a falling off in engine power with
'pinging' indicates when decarbonising
is due. The correct valve clearance is
,015 in. with the engine hot or cold.
THE AUSTIN 'A40' MAINTENANCE INSTRUCTLONS
General Check: Examine and, if
necessary, tighten al1 bolts and nuts such
as road spring clips, and body mounting
bolts.
Examine other parts, such as steering
connections, brake rods and tubing,
etc., neglect of any may be followed by
an expensive repair and inability to use
the vehicle fcr a lengthy period.

. T H E AUSTIN 'A40' MAINTENANCE INSTRUCTIONS
GENERAL MAINTENANCE
T H E following inforrnation covers those attentions essential to the satisfactory
operation of the vehicle, which are not already rnentioned either in 'Regular
Attentions,' or in the list of 'Service Attentions' norrnally entrusted to an Austin
deale r.
C O R R E C T lubrication is of the utrnost irnportance for the engine, which has to
operate at sustained high temperatures and speeds, and it is essential that only oils
of the highest quality and correct grade are used. Inferior or unsuitable oils will cause
excessive wear in an unduly short time.
Additives which dilute the oil or otherwise impair its efficiency must not be used,
neither should graphite compounds be rnixed with the oil as they may intefere with
the efficient working of the systern which ernploys very fine jets for the lubrication of
certain parts of the engine; also prernature choking of the oil filter rnay result.
Choice of Lubricants: The color or
appearance of an oil at atmospheric ternperatures gives no indication as to its
efficiency under operating conditions and
owners are advised to use only officially
recommended lubricants.
The letters S.A.E. followed by a nurnber constitute a classification of the
lubricant in terrns of viscosity or fluidity.
For instance, a low S.A.E. number
indicates that the oil is of low viscosity,
which means that it flows more readily
than oil with a high viscosity rating.
It will be appreciated, therefore, that
oil with a low S.A.E. number is essential
if easy starting is to be obtained in cold
weather, whereas in hot weather a higher
viscosity oil is desirable in order to keep
oil consumption within normal limits.
Upper Cylinder Lubrication: The use of
an upper cylinder lubricant is beneficia1
to the running of the engine and may be
added to the fue1 when the tank is
replenished. Carefully follow the manufacturer's instructions.
Impurities: Even the best oils in the
engine become contarninated during use,
with unburnt fuel, carbon, metallic particles, and moisture, and it is therefore
rnost important that the oil is changed
at the recommended rnileage.
Drain the crankcase when the oil is
warm and thoroughly fluid, since it will
then carry away as much of (he contamination as possible. Afterwards, if
necessary, the crankcase may be flushed
with a thin oil, but never in any circurnstances use kerosene.
Oil Level: The oil should never be
allowed to fall more than 4 inch from the
full mark on the dipstick. It is advisable
to wipe the dipstick before taking the
reading, which must only be taken when
the engine is stationary and the vehicle
on leve1 ground if a true result is to be
obtained.
Oil Pressure: The oil pressure gauge
indicates whether the oiling svstern is
working properly. It should be hoked at
occasionally while the engine is running
at normal speed.

be added to the coolant in the radiator.
Always flush the cooling systern
before adding an anti-freeze solution, 2nd
again when rernoving it in the Spring.
The rnanufacturers of anti-freeze will
provide a table indicating the quantity
to be used in providing full protection
against any degree of frost.
The strength of the soliition rnust be
maintained by topping up with antifreeze solution as necessary. Excessive
topping up with watrr will reduce the
degree of frost protection.
The following are officially approved
anti-freeze compounds: Srnith's 'Bluecol'; County Chernical Co. 'Chernico
Anti-Freeze'; and Johnson's
Velvol
Anti-Freeze'.
N.B.-If
a heater is fitted, under no
circumstances resort to draining the
cooling systern as an alternative to the
use of anti-freeze, due to the fact that
it is not possible to drain the heater
unit completely by means of the cylinder
block and radiator drain cocks.
HEATlNG AND DEMlSTlNG
T H E Smith built-in heating and demisting unit, as fitted to the Sedan, utilises the
waterin theenginecooling systern to heat air for circulation in the car interior and over
the windshield for dernisting and defrosting. The engine thermostat maintains a temperature of 158" to 167°F. in the cooling system, and since the thermostat enables the engine
to warm up very rapidly heat is available for the car interior soon after starting. In order
to obtain efficient helting in winter a therrnostat with a 180°F. rating should be installed.
An electrically driven b o x t e r blower, bolted to the left-hand side of the radiator
rnoiinting, draws air through the front grille and forces it along a large diametei flexible
pipe into the heater unit situated centrally on the bulkhead. Here it passes through a
water heated radiator into 11 distribution chamber where shutters, operated frorn thc
heater control panel, regulate its flow into the car interior.
the Heating and Ventilating System due
to the presence of objectionable odors,
dust, etc., in the air. Apart frorn this
condition, it will be found that this
control can be left in the 'Demist'
position except when it is desired to
rernove ice and frost forrnation on either
the interior o r outside of the windshield.
In this latter condition, the lever should
be moved to the 'Defrost' position.
N.B.-lf
cool air is required to the
windshield, the control should be in the
'Dernist ' position.
Ventilation Control: This is used in the
'Off' position when it is desired to
prevent the entry of fresh air, or when it
is required to devote the whole of the
blower output to windshield dernisting.
For Heating purposes the Ventilation
Booster Blower: This is used to increase
the air flow into the car and to the windshield, and is controlled by a pull-out
type switch situated on the right-hand
side of the heater control panel. Even
without the blower switched on, air will
be forced into the car and on to the
windshield by rarn effect due to the
vehicle's motion provided the appropriate valve in the Heating and Ventilation Unit is opened; but at low car speeds,
particularly if rnaxirnum heating o r
ventilation is required, the blower should
be switched on.
Windscreen Air Control: This is indicated on the quadrant by the words
'Dernist' and 'Defrost', and is only used
in the 'Oñ' position when it is desired
to prevent the entry of al1 fresh air frorn

THE AUSTlN 'A40' MAlNTENANCE INSTRUCTlONS
Control lever is placed anywhere between
the 'Warm' and 'Hot' positions according to the degree of heating required. For
Ventilation only in warm weather, the
lever is moved to the 'Cold' position.
N.B.-The
Ventilation Control cannot
be used in the 'Cold' position when
heated air is required on the windshield.
Summary of Control positions:(a) Warm weather: Ventilation control
in 'Cold' position, windshield air control
in 'Demist ' position.
Alternative settings when especially
good ventilation is required at head
rather than foot level: Ventilation control in 'Cold' position, windshield air
control in 'Defrost' position.
( b ) Cold weather: Ventilation control
set between 'Warm' and 'Hot' positions
according to degree of heating required:
windshield air control in Demist
position for demisting and 'Defrost'
position for removal of frost from
windshield.
Heater Unit (Commercial Vehicles and
Sports Model): The Smith Heater as
fided to the Commercial Vehicles and
Sports Model is of tlie re-circulation
type, ¡.e., its function is to heat and re-
circulate the air within the vehicle, and
therefore differs considerably from the
type fitted to the Sedan.
The heater consists of a small water
radiator, through which air is drawn,
heated and re-circulated by meins of a
fan driven by a small electric motor; this
being operated by a rheostat switch on
the control panel.
The heater is situated behind and
below the instrument panel, and warm air
is directed towards the feet. At the same
time a constant stream of warm air is
passed across the windshield via a duct
and nozzle built into the windshield rail
which ensures clear vision in conditions
when misting of the windshield is liable.
The heater radiator is supplied with
hot water from the engine cooling system
by means of a supply and return pipe,
and the water flow can be turned o n or
off at will, by operating the cock situated
on the right-hand side of the cylinder
block at the point where the water supply
pipe is connected.
This means that in winter warm air
can be circulated by use of the cooling
water, and in summer with the water
supply turned off, cool air can be circulated by the same means.
THE AUSTIN 'A40' MATNTENANCE TNSTRUCTIONS
BRAKES
T H E Girling hydraulic braking system employs two-leading shce brakcs at the front,
with a dual purpose expander unit on the rear brake shoes, enabling them to be
operated hydraulically or mechanically. A pisto1 grip handbrake mounted under the
fascia ooerates the mechanical linkaee to the rear brakes, while the pedal operates
hydrauli'cally on al1 four wheels.
Adjustment: The adjustment for taking
up wear in the brake shoe linings is
effected at each brake back plate; the
brake rods and linkage system should in
no circumrtances be altered. No attempt
should be made to adjust the brakes with
the handbrake on.
f i o n i Bra!tes: Firmly chock one of the
wheels and then jack the vehicle until the
front wheel to be adjusted is clear of the
ground. Fully release both the hexagonheaded adjuster bolts on the brake
backing plate by turning them in an anticlockwise direction. Then turn one of the
adjuster bolts in a clockwise direction
until the brake shoe concerned rubs
against the drum. Release theadjusterone
notch, o r until the brake shoe is just free
of the drum and then repeat the procedure for the second adjuster since on
the front brake assembly a separate
adjuster is provided for each shoe.
Repeat the adjustment for the other front
wheel.

shoes are then hard on, and the adjuster
should be turned back two full notches to
give the shoes the correct clearance from
the drum.
The adjuster can be turned a notch at a
time, and the engagement, which can be
heard and felt, is caused by the flat sides
of the cone on the inner end of the adjuster engaging with
the plungers
supporting the ends of the shoes.
One common adjuster is provided for
both shoes in the rear brake assembly and
the adjustment for both rear wheels is
identical. After adjustment the brake
pedal should be applied hard two o r three
'IHE REAK H I I A K l 5
times to centralise the brake shoesin their
drums.
Bleeding the Brakes: If any part of the
hydraulic brake system has been disconnected, it will be necessary to bleed
the system when the connections have
been reassembled, to ensure that the
hydraulic fluid is free of air bubbles.
Thers is one bleed nipple fitted on the
brake back plate assembly at each wheel.
Connect a rubber drain tube to one of
the brake bleed nipples and immerse the
open end of the tube in a j a r partly filled
with genuine braking fluid. Then fit a
spanner on the hexagon sides of the bleed
nipple and unscrew the nipple one full
turn. The brake pedal should now be
applied repeatedly with slow, full strokes
until the fluid entering the jar from the
drain tube is completely free of air
bubbles. The bleed nipple should now
be tightened with the spanner during a
down stroke of the brake pedal. Repeat
the whole operation on the other wheels.
It is important when bleeding the
brakes to check the fluid level in the
supply tank at frequent intervals and to
top-up as necessary to ensure that the
master cylinder is never starved of fluid.
Should air reach the master cylinder from
the supply tank it will be necessary to
bleed the whole of the system again.
Fluid which has just been bled from
the system should never be used for
topping-up the supply tank immediately,
since it will be to some extent aerated. It
must therefore be allowed to stand for an
hour or two before it can safely be used
again. Dirty fluid must be discarded since
grit o r other foreign matter in the system
will seriously affect braking efficiency, and
cause unnecessary wear.
TIRES
TIRE that loses more than three to four pounds per square inch in a week should
be suspected of a slow puncture, but first make sure that the valve is not the cause.
The pressures given below should be maintained to ensure long life to the tires and best
running and riding conditions for the vehicles.

The tires should be changed over at
regular intewals to give each ;¡re the
chance of giving the maximum service
with even wear. T o do this, every 2,000
miles, with the left side jacked up, place
the spare on the left side rear. Move left
side rear to left front side.
Jack ~ i on
p the right side. Move left side
front to right side front, right side front
to right side rear, and right side rear to
spare.
This gives each tire a new position
each move, and includes a period of rest
during one full circuit.
T H E jacking of the Sedan is effected by a Stevenson telescopic jack which operates
from a central cross-member of the chassis frame. There are two positions for the
jack, enabling either the right or left side of the vehicle t o be raised.
Operation: T o jack up the Sedan first
apply the handbrake and then lower the
Stevenson jack into position, through
either the left or right opening in the
floor of the vehicle at thc side of the front
seats.
Ensure that the boss on the jack fiilly
engages with the recess in the chassis
frame cross-member and that the base of
the jack has a firm footing on the ground;
then proceed to wind down the jack with
the wheelbrace.
lmmediately the vehicle is felt lo lift,
again check that the boss is correctly
located in the chassis socket.

There is a recess across the jack lifting
platform, which allows the strengthening
ring on the spring plate to locate.
For lifting the rear wheels, place the
lifting platform across the lowest spring
leaf, to the rear of the axle, with the lipped
end on the outside of the spring and up
against the spring U-bolt; this avoids
any turning movement.
The jack is operated with the vehicle
starting crank, an intermediate length of
rod being provided with the jack t o allow
it to reach the described positions easily.
Changing a Wheel: Before removing a
wheel ensure that the vehicle is securely
jacked with the handbrake firmly on and
if on a hill it may be advisable t o scotch
one o r both of the wherls.
For access t o the wheelnuts lever out
the wheel center by inserting either a coin
or a screwdriver in one of the slots under
its rim.
When refitting the wheel, tighten the
nuts alternately and securely before
removing the jack. Finally test the nuts
with the wheel on the ground.
FUEL SYSTEM
T H E FUEL PUMP is bolted to the engine low down on the left side, and has an
inlet pipe from the rear tank and an outlet pipe to the carburetor. The priming
lever is on the side. When reaching towards the pump remember that it is close to the
exhaust pipe, which may be hot.
If gasoline appears t o be leaking at the
edge of the diaphragm tighten the cover
screws alternately and securely. Sometimes such leakage may actually come
from one of the pipe fittings, causing the
fue1 t o run down the pump and collect
round the diaphragm flange.
Fuel pump service is available at al1
Austin dealers. They are stocked with
parts and fittings for any repairs and
ndjustments that may become necessary.
T H E CARBURETOR is of the Zenith
downdraft type and apart from the
occasional cleaning of the inlet pipe
filter and the jets as outlined in 'Regular
Attentions', should need little maintenance.
Controls: From time to time it may be
advisable to ensure that the choke and
throttle controls are operating freelythe strangler flap must open andclose
fully, and the throttlecontrol must ieturn
fully against its stop in theidlingposition.
Slow Running: The slow running of the
engine is controlled by an air mixture
screw and a throttle stop adjusting screw.
The screw is normally set one nnd a half
turns from the fully closed position and
the throttle stop adjusting screw is set
t o give the smoothest idling speed, consistent with a quick response from the
engine to a sudden opening of the
throttle when the engine is warm.
A weak mixture may cause uneven
slow-running and this may be correctecl by

turning the ir regulating screw clockwise
to enrich the mixture. D o not make
the mixture too rich or the engine will
tend to choke when running slowly.
S H O U L D any fault develop the owner is advised to contact an Austin dealer. The
following are adjustments and replacements which an owner should be able to
Battery: Keep the trrminals and battery
top clean. Also ensure the security and
good electrical contact of the tattery
positive ground strap on the engine rear
mounting plate, and chasis member.
Headlight Adjustment : The alignment
of the lights is very easily carried out.
The light beams must be set straight
ahead parallel to the road and to each
other.
To carry out the adjustment, proceed
as follows:Remove the front rim by unscrewing
the rim securing screw and lifting off the
rim, which is split to facilitate removal.
Next remove the rubber dust excluder,
when three spring-loaded adjustment
screws will be visible, by means of which
the setting can be altered as desired. For
example, if the beam needs swinging to
the left, the screw on the left side of the
Light Unit must bc tightened.
NO focusing device is necessary with
this type of light, since the bulb is manufactured in such a way that the filament is
always positioned correctly with respect
to the foca1 point of the reflector.
Removal of Light Unit: T o remove the
Light Unit, remove the front rim and dust
excluding rubber as previously described
above. Press the Light Unit in against
the tension of the adjustment screw
springs and tum it in a n anti-clockwise
direction until the heads of the screws
can be disengaged from the slotted holes
in the Light Unit rim. D o not disturb
the setting of the screws when removing
the Light Unit or the alignment will be
altered.
The bulb is made accessible by removal
of the back shell at the rear of the
reflector.

BODYWORK
D U S T on the vehicle rnay be lightly flicked off with a duster, but on al1 other occasions
the vehicles should be thoroughly washed and dried before a non-abrasive polish is
used. Any attempt to rub dirt off the vehicle will result in severe scratching of the srnooth
surface of the high luster enamel. Grease and tar splashes must be very carefully removed
with a soft rag dipped in gasoline.
Washing and Polishing: Frequent washing with clean cold water will greatly
assist in maintaining the high luster
finish of the paintwork.
When washing the vehicle, start at the
top and work downward, using a slow
flow of water and a sponge free from grit
and oil. Leather off al1 surplus moisture.
Should the finish become dull after
several months, the use of a liquid polish
of reputable manufacture will restore it to

a vacuum cleaner if available.
The carpets should be kept free from
dust and grit by vigorous brushing with
a stiff brush or by using a vacuum cleaner.
Periodically the carpets and felts should
be removed and thoroughly beaten.
Other Attentions: Doorlocks, hinges,
and other small working parts should be
given a drop of oil occasionally and
checked for security. Sliding seat runners
will benefit if very lightly smeared
with grease periodically, but never grease
the runners of the sliding roof panel.
application of a good quality wax polish,
after the vehicle has been thoroughly

T H E gun, as supplied, is used for forcing lubricant through the nipples. Charge the
gun by unscrewing the end cap and fill to its capacity.
fill the gun with the correct oil and replace the cap, hold the gun firmly in the
left hand, unscrew the cap approximately
two tums and then gently force the steel
cylinder into the gun. This will force the
oil to the top of the barre1 and displace
any air that may have been included in
the filling process; the air can be heard
distinctly coming out of the threads of
the cap and when oil begins to ernerge
the cap should then be tightened. After
lubricating a point, it is most essential
that the disconnecting process should
be made with a sideways breaking
movement and not pulled directly away;
any attempt to disconnect it by pulling
directly away will have a tendency to
break the soring d i o in the nozzle of the
gun and a t t h e s a k e time to extend the
cylinder, thereby sucking in air.
T o enable the steering box and rear
axle to be topped up as and when necessary, there is a special adaptor provided.
The procedure is as follows: Rernove the
end cap and extend the steel cylinder as
far as possible, fill the gun with the
recommended oil and then screw o n the
adaptor in place of the end cap.
Remove the steering box or rear axle
filler plug, insert the adaptor end into the
filler orifice and force the steel cylinder
into the gun body. This will quickly
empty the gun's contents into the cornponent concerned.
Replace the filler plug after ascertaining
that the cornponent has Oeen topped up
to its correct level.

Oiling Technique: Always make sure
that the nipple on the chassis cornponent
about to be lubricated is clean before
applying the gun. Push the gun body
hard and repeat the strokes according
to the arnount of lubricant required inthe
component. Wherever possible, watch
for old oil exuding from the cornponent
concerned, since this is proof that the
new oil is being forced in. A nipple which
refuses to pass oil should be removed and
cleaned. This is best achieved by leaving
the nipple to soak for a short time in
kerosene.
Should difficulty be experienced in the
operation of the gun it is probably due to
air locks. This can be easily overcome
by ccirryingout !he fullowing procedure: Extend the steel cylinder as fi!r cis po\sible.

SERVICE ATTENTIONS
T H E following list of attentions are those which cover components o r accessories not
common to the 'A40' Sedan and Commercial Vehicles.
All other attentions should be carried out as recommended in the previous pages.
EVERY 2,000 MILES
Carburetors: Remove the knurled cap
at the top of each carburetor and add a
few drops of oil to the suction piston
dampers.
Air Filters: Access to the filter element
is gained by removing the top cap, which
involves the release of only one screw.
Withdraw the element, hold upright and
tap gently or brush lightly on outside.
Jf compressed air is available, the element
can be effectively cleaned by directing a
jet of air on to the inside surface of the
filtering material, thereby blowing out
the dust particles impinged on the outer
surface. Any element contaminated with
oil, grease, paint, etc., should be washed
thoroughly in petrol o r other suitable
solvent and allowed to dry before being
replaced.
EVERY 5,000 MILES
Carburetors: The flow of fue1 at the
carburetor inlet unions to the float
chambers should be checked, and, if
necessary, the filters in those unions
should be cleaned.
Disconnect the float chamber fue1
supply pipes (when the filters may be
taken out and cleaned), slacken the float
chamber cap nuts, and unscrew the float
chamber holding-up bolts. The chambers
themselves can then be removed for
cleaning.
Be careful not to lose the float levers.
pins and needles.
T H E A I R FILTERS
A and R are t h e lrwo lurl intakes l o Lhe carburelors
which should be checked for lighlness occasionally.
EVERY 10,000 MILES
Carburetors: Clean out the suction
assembly by removing the two securing
screws and lifting off the body in the same
plane to avoid damage to the needle.
Lift out the hydraulic damper and wash
the assembly in gasoline. Dry thoroughly,
refit, and replenish the damper with oil.
When fully re-assembled, lift the piston
to its fullest extent, thus expelling the
surplus oil through the top cap, and at
the same time lubricating the rod.
T H E AUSTlN 'A40' MAINTENANCE INSTRUCTIONS
This is the only part which requires
lubrication, the piston itself and the inside
of the suction shamber should be left dry.
The Air Filters: Remove the top caps,
and renew the elements.
Spark Plugs: Renew the spark plugs,
using either Champion NA8 Long
Reach or Lodge HL. 14. The gaps of
these plugs should be maintained at
,025 ins.
GENERAL MAINTENANCE
T H E following information covers those attentions essential to the satisfactory
operation of the car, and wliich are not already mentioned in the list of 'Regular
Attentions' or 'Service Attontions' given for the 'A40' Somerset.
FUEL SYSTEM
THE CARBURETORS:
The twin S.U. Carburetors are carefully balanced to ensure that the engine
runs perfectly, and it is therefore important that only qualified'people are
allowed t o attend to any major faults:Should the engine run badly, after
having previously given good results,
look for a minor fault and not a major
one.
The two regular maintenance attentions
necessary are listed under 'Every 2,000
and 5,000 Miles,' and are (1) oiling the
piston dampers and (2) cleaning the inlet
filters.
T o obtain the best results always maintain the carburetors in a scrupiilously
clean condition, and occasionally lubricate the throttle spindles and choke
linkages with oil.
In the event of poor running, first
inake sure the pistons are able to move
freely; if they are not, the causes may be
as follows:Dirt in the suction chambers, the cure
for which is given under 'Every
10,000 Miles.'
A bent hydraulic damper spoke. Cure:
Straighten or replnce.
A bent jet needle. Cure: Replace.
Straightening is not recommended,
except in an emergency.
An incorrectly centered jet. Cure:
Re-center
in
the
following
manner:-Screw the jet-adjusting nut
to its weakest position and slacken the
jet screw. Gently tap the jet head until
the piston falls freely, striking the
bridge with an audible click while
gradually re-tightening the jet screw.

If the first effort is not successful,
repeat the process.
To Adjust the Carburetors: The only
adjustments are by means of the jet
adjusting nuts and the throttle stop
screws. First synchronise the throttles
by slackening one of thespindleiiniversal
joint clamp screws, unscrewing both
throttle-stop screws and shutting both
completely-then
re-tighten the clamp
screw.
Another method is to listen to the Iiiss
of each carburetor with o piece of tube,
one end of which should be placed
adjacent to the carburetor intake and the
other in the ear, then adjust throttles until
the hiss is equal. Now lift the piston of
each carburetor in turn; if this causes the
engine to speed-up, the rnixture is too
strong and the jet adjusting nut should be
screwed up. If the engine stops irnrnediately the rnixture is too weak and the jet
should be lowered (unscrewed). If the
engine just falters or continues t o run,
but unevenly, then the adjustrnent is
correct. The only rnethod of altering the
rnixture strength throughout the whole
speed range is by changing the jet
needles. T o d o this, rernove the two
screws round the base of the suction
charnber, then lift off the whole assernbly,
taking the utrnost care not to bend the
needle. Slacken the needle nrub screw
and withdraw the needle: it-sh0dd be
refitted with its shOulder flush with the
face of the piston. Sorne needles are rnade
on a watchrnaker's lathe and have
square shoulders; others on a centerless
grinder and have round shoulders, the
Dart constituting the shoulder is shown
in the illustratioñ.

HOULD any fault develop the owner is advised t o contact an -4ustin dealer. The
Sfollowing are adjustrnents and replacernents which an owner should be able to
undertake.
Removal of Light Unit: T o rernove the
Light Unit, rernove the front rirn and
dust excluding rubber as previously
described above. Press the Light Unit in
against the tension of the adjustrnent
screw springs and turn it in an anti-clockwise direction until the heads of the
screws can be disengaged frorn the slotted
holes in the Light Unit rirn. D o not
disturb the setting of the screws when
rernoving the Light Unit ot the alignrnent will be altered.
The bulb is rnade accesible by
rernoval of the back shell a t the rear of
the reflector.
Bulb Fitting :
Headlights: Rernove the light rirn as
described under 'Headlight Adjustrnent
to gain access to the bulbs.
Undo the bayonet catch a t the back of
the reflector, and the headlight bulb can
be removed.
Parking Lights: Move back the rubber
l i at
~ the bottorn of the light and insert a
coin under the glass rirn. Yhis allows the
glass and rirn to come cornpletely away,
leaving the bulb in its socket. When
Battery: Keep the terrninals and battery
top clean. Also ensure the security and
good electrical contact of the battery
positive ground strap on the engine rear
rnounting- - late, and chassis mernber.
Headlight Adjustment: The alignrnent
of the lights is very easily carried out.
The light bearns rnust be set straight
ahead parallel to the road and t o each
other.
T o carry out the adjustrnent, proceed
as follows:Rernove the front rirn by unscrewing
the rirn securing screw and lifting off the
rirn, which is split t o facilitate rernoval.
Next rernove the rubber dust excluder,
when three spring-loaded adjustrnent
screws will be visible, by rneans of which
the setting can be altered as desired. For
example, if the bearn needs swinging t o
the left, the screw on the left side of the
Light Unit rnust be tightened.
N o focusing device is necessary with
this type of light, since the bulb is rnanufactured in such a way that the filarnent
is always positioned correctly with
respect to the foca1 point of the reflector.

replacing the rim and glass lacate the top
edge first, then allow the rubber lip or
cup to overlap the rim, making a watertight joint.
Stop- and Tail-lights: Move back the
rubber lip, insert a coin or screwdriver
blade under the glass retaining collar and
gently lever the collar out from the light
body. This will enable the light glass to
be completely removed, leaving the bulb
accessible in its socket.
Rear License Plate Light: Undo the one
bolt and the cover can be removed t o
give access t o the bulb.
Panel Lights: Access to the bulbs is
gained by swinging aside the spring clips
a t the back of the instrument panel and
pulling out the bulb holders, from which
the bulbs may easily be unscrewed.
Ignition and Hi-Beam Warning Lights:
The bulbs can be unscrewed from their
holders when pulled out from the
back of the warning light panel.
Direction Signals: T o remove a bulb,
switch on the signal, hold it in the out
position and then switch off. Withdraw
the screw on the underside of the arm
and slide off the metal plate, when the
bulb can be renewed. When replacing the
metal plate, slide it in an upward direction so that the plate engages with the
slots on the underside of the spindle
bearing.
Fuses: The fuse unit is situated adjacent to the voltage regulator and cutout on the right-hand side of the engine
bulkhead and contains two fuses and two
spare.
One fuse protects the accessories which
are operative only when the ignition is
switched on (e.g., stop-lights, fue1 gauge,
and direction signals). The other fuse
protects those accessories which can be
opxated independently of the ignition.
If a new fuse blows, the cause of the
trouble must be found.

WIRING DIAGRAM
BODYWORK
D U S T on the car may be lightly flicked off with a duster, but on al1 other occasions
the car should be thoroughly washed antl dried before a non-abrasive polish is used.
Any attempt to rub dirt off the car will resiilt in severe scratching of the smooth surface
of the hiph luster enamel. Grease and tar splashes must be very carefully removed with a
soft rag dipped in gasoline.
The Folding Top: Before the top can be
lowered the following preliminary operations must be carried out:First, release al1 the top fasteiiers at
the rear of the car. Next pul1 the rear
seat squab forward and remove the top
well side covers, after which the rear
window must be separated from the
hood, by releasing the press studs, and
then placed in the rear compartment of
the top well-this being most important
if damage to the celluloid window is to be
avoided.
Finally lift the top rail clear of its
two securing pegs situated above the
windshield.
The top itself can now be lowered,
although while doing so it will be necesary t o press inwards on the jointed rear
top support, in order to prevent it
fouling the rear edge of the top well,
and then downward pressure must be
exerted on the top linkages in order
t o straighten them-this
being most
important if the top is t o take up its
correct position in the well. Rol1 up the
front part of the top and stow it as far
back as possible in the top well. I t is
essential that the whole top assernbly
be pressed very compactly into the well
provided, in order that the rear seat
squab may be returned to its normal
vosition and fastened. Finally.
- .secure the
iop well side covers.
Raising the top is an exact reversal
of the above procedure.
The top should be cleaned regularly,
particularly when it is new, to combat
any initial chemical reaction which may
occur during its early life. T o clean the
top it is only necessary to use soap and
water and a stiffor semi-stiff brush of the
nailbrush type. If dust and grime has
been allowed t o remain on the top for a
long time so that it has become really
dirty, and the ordinary soap and water
method is not completely effective, then
clear methylated spirit may be used with
the same type of bmsh. It will be found
that by cleaning by the methods outlined
the surface will continue to look as good
as new.
Washing and Polishing: Frequent washing with clean cold water will greatly
assist in maintaining the high luster
finish of the paintwork.
When washing the vehicle, start at the
top and work downward, using a slow
flow of water and a sponge free from grit
and oil. Leather off al1 survlus moisture.
Should the finish become dull after
severa1 months, the use of a liquid polish
of reputable manufacture will restore it to
its original condition. An occasional
application of a good quality wax polish,
after the vehicle has been thoroughly
washed and cleaned, will help considerably towards preserving the vehicle's
appearance.
Chromium plated parts should be
washed with soap and warm water and
cleaned with a damp leather. On no
account should metal polish or any kind
of abrasive substance be used.
The leather upholstery and trimming
may be cleaned with a damp cloth and
polished when dry with furniture cream.
The carpets should be kept free from
dust and grit by vigorous brushing with
a whiskbroom or by using a vacuum
cleaner. Periodically the carpets and felts
should be removed and thoroughly
beaten.
Other Attentions: Door locks, hinges,
and other small working parts should be
given a drop of oil occasionally and
checked for security. Sliding seat runners
will benefit if very lightly smeared with
grea se periodically.
