4a.If boat is fitted with a packing gland (stuffing box) connected to the stern
tube with a length of reinforced hose (self aligning type), disconnect the2 parts from the stern tube and slide them forward on the shaft. *Go to step #5 at this point.*
Self Aligning Packing Gland. Self Aligning Packing Gland, Bolt Type.
4b.If boat is fitted with a rigid type packing -gland with a threaded tube
section, a packing nut, and a locking nut; a Stern Tube Adaptor (female
thread at one extremity and hose barbs at the other) should be installed.
Stern Tube Adaptors are available from LEMANIA COMPANY in a variety of pipe
sizes. Consult us for your specific application.
An alternate method if an adaptor is not available for your application is
to coat the threads with a marine type sealant such as G.E. 5200 and let
set before fitting of Bellow/Friction Ring Assembly. This will provide a
smooth surface on which to install the Bellow/Friction Ring Assembly.
First remove the packing nut, the locking nut and the packing (flax).
*Go to step #6 at this point.*
Rigid Type Packing Gland. Stern Tube Adaptor.
•
4c.If boat is equipped with a rigid, bolt type, packing gland with 2 studs and
a flanged piece that compresses the packing when it is tightened down over
the studs; this flanged piece should be removed and then reinstalled in the
following manner:
*Proceed with step #6 of the instructions at this time, then return to #4c.*
First, remove the flanged piece and all packing material. Next, coat the
outside flat surface of the flanged piece with a marine type sealant. Now
reinstall the flanged piece in the opposite direction from its original
position (protruding cuff no longer inside of packing gland housing but on
the contrary facing out). This should now provide a suitable section of pipe
on which to clamp the Bellow/Friction Ring Assembly.
*Skip ahead to #7 at this point.*

5. Calculate misalignement between stern tube and shaft using the following
procedure:
Measure distance between shaft and top of stern tube, then measure distance
between shaft and bottom of stern tube. The difference between these two
measurements is the amount of vertical misalignement. Repeat this procedure
for horizontal misalignement, measuring between shaft and left and right
(port & starboard) sides of stern tube.
If either the vertical or horizontal misalignement exceeds 3/16" (.1875"),
then you must fit a Stern Tube Alignement Kit, available from LEMANIA
COMPANY, before installing the LASDROP Shaft Seal as this excessive amount
of misalignement would prevent the seal faces from seating properly and
would cause the unit to leak.
•
WARNING: INSTALLATION OF SHAFT SEAL WITHOUT AN ALIGNMENT KIT ON A STERN TUBE
MORE THAN 3/16" OUT OF ALIGNMENT, AS DETERMINED BY ABOVE PROCEDURE, WILL
VOID THE WARRANTY.
6. Uncouple shaft from transmission. Disassemble and remove coupling from shaft
Slide shaft away sufficiently to allow for removal of existing seal parts
and installation of Bellow/Friction Ring Assembly and Shaft Ring Assembly.
7. Polish shaft with fine emery cloth to ease installation of Shaft Ring
Assembly. Do not omit to polish section of shaft which has been pushed back
into the stern tube.
8. CAUTION: Do not use any tools to handle either Friction Ring or Shaft Ring
Assembly as the polished surfaces of these parts are very easily damaged.
•
Install Neoprene or Reinforced Hose Insert in stern tube end of Bellow if
needed to act as a spacer between the Bellow and the tube.
10.Slide Bellow/Friction Ring Assembly over the shaft. Slip Bellow over stern
tube being careful not to install it beyond clamping location.
Adjust Bellow on stern tube if needed to make Friction Ring seal face
PERPENDICULAR TO SHAFT. Hose Barb Fitting should be pointed straight up or
at a maximum angle of 45 degrees from the top. Tighten Hose Clamps.
11.Make sure Hose Clamps securing Friction Ring to the Bellow are tight but DO
NOT OVERTIGHTEN them as this might distort the Friction Ring and could
prevent the seal faces from sealing properly.
12.Install 0-Ring, Compression Screws and Clamp Srew in Shaft Ring Assembly if
they are not already in place. Coat 0-Ring in Shaft Ring Assembly and shaft
with a light film of oil to facilitate installation of Shaft Ring Assembly.
Slide Shaft Ring Assembly over the shaft, with Seal Ring (polished surface,
no screws) facing the Bellow/Friction Ring Assembly, until it is just
touching the Friction Ring. Trace a mark on the shaft at the end of the
Shaft Ring Assembly (a pencil or fine felt tip marker works best for this).
Slide Shaft Ring Assembly toward the Bellow/Friction Ring Assembly,
compressing the Bellow, until the end of the Shaft Ring Assembly is 1/4" to
3/8" (.250" to .375") from the mark on the shaft. Tighten the Clamp Screw
until the Shaft Ring Assembly can no longer be moved on the shaft. This
should be approximately 1/2 turn past tight and should leave a small gap
between the two sections of the clamp ring (this gap should be wide enough
to slide a sheet of paper in). Tighten the compression screws.

13.Slide the Protective Cover over the Shaft Ring Assembly and press it on to
the small recess on the end of the Friction Ring.

WARNING: DO NOT COMPRESS BELLOW MORE THAN 3/8" (.375") as this will cause
accelerated wear of friction surfaces and could lead to seal failure.
COMPRESSING BELLOW/FRICTION RING ASSEMBLY MORE THAN 3/8" AS DESCRIBED ABOVE
WILL VOID THE WARRANTY.

14.If the vessel on which this seal is being installed has a maximum hull
speed under 12 knots (Displacement Hull), follow the procedure described
in step # 15: Vent Line Installation.
If the vessel on which this seal is being installed has a maximum hull
speed over 12 knots (Planing Hull), follow the procedure described in step
# 16: Water Injection Installation.
15.Vent Line Installation: The purpose of the Vent Line Intallation is to
prevent the formation of potentially' damaging air pockets inside the shaft
seal. Such air pockets could lead to seal failure if the seal faces are
allowed to run without the benefit of water cooling and lubrication. The
Vent Line will allow any air that finds its way into the shaft seal during
manoeuvers or haulout to be immediately vented out.
Using one of the Mini Clamps provided, connect the 1/4" I.D. Reinforced
Water Hose to the Hose Barb Fitting on the Friction Ring. Be sure to fully
slide the Hose over the Hose Barb Fitting, this will prevent the Hose from
accidentally working loose during operation. Note: A soapy water solution
can be helpful in sliding the Hose over the hose barbs.
The Hose can then be routed to a safe and secure position WELL ABOVE THE
HIGHEST POSSIBLE WATERLINE LEVEL. The Hose should be well secured with the
Cable Ties supplied with the kit, and/or with cable clamps or any other
type of fitting that will support and maintain the Hose in the desired
location without crimping or otherwise restricting the opening of the Hose.
•
WARNING: If the Hose is not well secured and the open end should drop to a
point below the waterline, this would cause a serious leak which if left
unattended could present a problem to the flotation of the vessel.
The open end of the Hose should be well protected so as not to allow any
foreign matter (dirt or other) to plug the opening. This can best be
achieved by shaping the open end of the Hose into a gooseneck with the
opening facing down.
16.Water Injection Installation: The purpose of the Water Injection Intallation
is to provide a source of supplementary water lubrication to the seal faces.
This can be required should the water present in the shaft log and Bellow
during normal operation drain out or be vacuumed out when the hull reaches a
planing condition.
Using one of the Mini Clamps provided, connect the 1/4" I.D. Reinforced
Water Hose to the Hose Barb Fitting on the Friction Ring. Be sure to fully
slide the Hose over the Hose Barb Fitting, this will prevent the Hose from
accidentally working loose during operation. Note: A soapy water solution
can be helpful in sliding the Hose over the hose barbs. 10131 N.W. 46th Street, Sunrise, Florida 33351, (305) 742 3873

The Hose should then be connected to the raw water cooling discharge
of the engine. This connection can be made at one of the clean out plugs on
le,Nthe raw water jacket of the exhaust manifold. Use one of the Bronze
1/4.IReducing Bushings provided and one of the Heat Stabilized Nylon Hose Barb
Fittings to make the connection. If you should need a different size
Reducing Bushing contact LEMANIA COMPANY for a direct exchange. Be sure to
securely clamp the Hose onto the Hose Barb Fitting using the second Mini
Clamp provided.
An Alternate method of connecting the Water Injection Hose is through a "T"
fitting installed in the hose located between the raw water dicharge of the
engine and the muffler (goose neck). "T" Fittings for different hose sizes
are available directly from LEMANIA COMPANY.
Be sure to leave enough slack in the Water Injection Hose at the Friction
Ring connection to allow for movement of the Bellow/Friction Ring Assembly.
17.The LASDROP Shaft Seal may drip during the first few hours of operation
until both friction parts have mated to one another.
18.REPLACEMENT PARTS: Order directly from LEMANIA COMPANY. A complete
inventory of parts is maintained for Immediate Delivery.
19.IMPORTANT: The LASDROP Shaft Seal must be located in a protected and
isolated condition. No foreign objects can interfere with its movement.
If your LASDROP is not protected and isolated, consider some kind of
shrouding. This will also serve to protect anyone from coming into contact
with the moving parts of the shaft seal during operation.
WORK ON OR AROUND THE LASDROP SHAFT SEAL WHEN THE SHAFT IS
4/1 WARNING:NEVER
ROTATING. You could be seriously injured if you come into contact with the
moving parts of the shaft seal, or if an item of your clothing should
become entangled on these moving parts when the shaft is rotating!

ADDENDUM TO 02/21/89 VICP INSTRUCTIONS FOR A & B MODEL LASDROPS ONLY
This addendum is intended for LASDROP Installations on boats powered by
small, flexibly mounted, diesel engines. ie: Yanmar, Volvo, BMW, etc... Or on
boats where the driveline set up is such that the driveshaft is allowed to move
axially (fore & aft) in excess of 1/16" and/or radially (side to side, runout,
shaft whip, etc...) in excess of 0.010" (10/1000"). ie: Aqua Drive or Scatra
instalations, shafts with 3' or more unsuported, etc...
On any Installation as described above or in any case where the drive shaft
might be subjected to noticeable vibration or movement, the distance that the
bellow should be compressed, as outlined in step #12 & #14 of the Installation
Instructions, will need to be increased in proportion to the severity of the
shaft movement or vibration.
In most cases where such an adjustment needs to be made, it is recommended to
start with 3/8" to 1/2" compression and increase this value in 1/8" increments
as needed. In no case, however, should the amount of bellow compression exceed
the values as listed in the table below!
