Engine preservation
Introduction
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is withdrawn from service for a prolonged period.
Use these procedures after the engine is withdrawn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 ll it with the preservative
fuel. POWERPART Lay-Up 1 may be added to
the normal fuel to change it to a preservative
fuel. If preservative fuel is not used, the system
may be completely lled with normal fuel but the
fuel must be drained and discarded at the end
of the storage period together with the fuel lter
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 lter.
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 proprietary preservative uid instead of the
lubricating oil. If a preservative uid is used, this
must be drained and the lubricating oil sump
must be lled to the correct level with normal
lubricating oil at the end of the storage period.
6. Drain the coolant circuit, see page 18. In order to
protect the cooling system against corrosion, ll it
with an approved antifreeze mixture because this
gives protection against corrosion.
Caution: If protection against frost is not
necessary and a corrosion inhibitor is to be used,
it is recommended that you consult the Service
Department, Wimborne Marine Power Centre, refer
to company address list on page 6.
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.
Caution: The raw water system cannot be drained
completely. If the system is drained for engine
preservation purposes or for protection from frost,
the system must be lled again with an approved
antifreeze mixture, see page 45.
9. Remove the impeller from the raw water pump
and put the impeller in a dark place for storage.
Before the impeller is tted at the end of the
storage period, lubricate lightly the blades and
each end of the impeller and the inside of the
pump with Castrol Spheerol SX2 grease or
glycerine.
Caution: The raw water pump must never run in a
dry condition because this will damage the impeller
blades.
10. Remove the atomisers and spray POWERPART
Lay-Up 2 for one to two seconds into each
cylinder bore with the piston at BDC. Slowly turn
the crankshaft one revolution and then t the
atomisers, complete with new seat washers and
new dust seals.
11. Spray POWERPART Lay-Up 2 into the induction
manifold. Seal the manifold with waterproof tape.
12. Remove the exhaust pipe. Spray POWERPART
Lay-Up 2 into the exhaust manifold. Seal the
manifold with waterproof tape.
13. If the lubricating oil ller is tted onto the rocker
cover, remove the ller cap. If the lubricating oil
ller is not tted onto the rocker cover, remove
the rocker cover. Spray POWERPART Lay-Up
2 around the rocker shaft assembly. Fit the ller
cap or rocker cover.
14. Disconnect the battery. Then put the battery
into safe storage in a fully charged condition.
Before the battery is put into storage, protect its
terminals against corrosion. POWERPART Lay-
Up 3 can be used on the terminals.
15. Seal the vent pipe of the fuel tank or the fuel ller
cap with waterproof tape.
16. Remove the alternator drive belt and put it into
storage.
17. In order to prevent corrosion, spray the engine
with POWERPART Lay-Up 3. Do not spray the
area inside the alternator cooling fan.
