7 Clean the contact surfaces of the pump body and
the end plate. Apply jointing compound to a
new joint and fit it to the body with the wide area
of the joint over the eccentric plate (Al) in the
body. Fit the end plate and tighten the end
plate screws.
8 Apply a high melting point grease (for example
Shell Alvania R2) to the drive housing and to the
drive components.
9 Fit the pump to its adaptor plate with a new joint
between the pump and the plate. Tighten the
four pump setscrews.
10 Connect the hose connections at the pump.
11 If necessary, open the seacock. How to clean the
tube stack of the heat exchanger
If there are hard deposits or debris in the tubes, the
best method to clean them is to use a non-
caustic solution which is approved by the
manufacturer.
If the deposits or the debris are soft, the tubes
can be cleaned with a steel rod pushed through
the tubes in the opposite direction to the water
flow. Ensure that the rod does not damage the
tubes.
To obtain access to the tube stack
1 Drain the circuits of the cooling system.
2 Loosen the support clips of the outlet pipe of the
heat exchanger and disconnect the pipe from the
front end cap of the heat exchanger.
3 Loosen the clips of the neoprene end caps and
remove the caps. The tubes can now be
checked for restriction and cleaned, if necessary.
4 Ensure that there is an equal protrusion of the
tube stack through each end of the housing
before the end caps are fitted.
Engine Preservation
The recommendations indicated below are
designed to prevent damage to the engine when it
is withdrawn from service for a prolonged
period. Use these procedures after the engine
is withdrawn from service. The instructions for
the use of POWERPART products are given on
the outside of each container.
Procedure
1 Completely clean the outside of the engine.
2 When a preservative fuel is to be used, drain the
fuel system and fill it with the preservative fuel.
POWERPART Lay-Up 1 can be added to the
normal fuel to change it to a preservative fuel.
If preservative fuel is not used, the system can
be completely filled with normal fuel but the fuel
must be drained and discarded at the end of the
storage period together with the fuel filter
canister.
3 Operate the engine until it is warm. Then correct
leakages of fuel, lubricating oil or air. Stop the
engine and drain the lubricating oil from the
sump.
4 Renew the canister of the lubricating oil filter.
5 Fill the sump to the full mark with new and clean
lubricating oil and add POWERPART Lay-Up 2
to the oil to protect the engine against corrosion. If
POWERPART Lay-Up 2 is not available, use a
correct preservative fluid instead of the
lubricating oil. If a preservative fluid is used, this
must be drained and the lubricating oil sump
must be filled to the correct level with normal
lubricating oil at the end of the storage period.
6 Drain the coolant circuit. In order to protect the
cooling system against corrosion, it is neces-
sary to fill it with a coolant that has a corrosion
inhibitor. If protection against frost is necessary, use
an antifreeze mixture. If protection against frost
is not necessary, use water with an approved
mixture of corrosion inhibitor.
7 Operate the engine for a short period in order to
circulate the lubricating oil and the coolant in the
engine.
8 Close the seacock and drain the raw water cooling
system. If a lubricating oil cooler is fitted to the
Hurth reverse gearbox and protection against
frost is necessary, disconnect the top hose at the
cooler and inject 50ml (0.1 UK pint) of undiluted
antifreeze into the cooler.
9 Remove the end plate from the raw water pump and
lubricate the impeller and the inside of the pump
with Marfak 2HD grease or glycerine. If
necessary, glycerine can be put in the inlet
connection of the pump but the engine must be
turned to circulate the glycerine through the
pump.
Attention: The raw water pump must never run
in a dry condition because this can damage the
impeller blades.
10 Remove the atomisers and spray POWERPART
Lay-Up 2 into each cylinder bore. If this is not
available, clean engine lubricating oil will give
a degree of protection. Spray into the cylinder
bores 140m1 (0.25 pint) of lubricating oil divided
evenly between the cylinders.
11 Slowly turn the crankshaft one revolution and
then fit the atomisers, complete with new seat
washers.
12 Remove the air filter or the induction cap. Spray
POWERPART Lay-Up
manifold. Seal the manifold with waterproof
tape.
13 Remove the exhaust pipe. Spray POWERPART
Lay-Up 2 into the exhaust manifold. Seal the
manifold with water proof tape.
