OIL RECOMMENDED FOR PRESERVATION OF FUEL SYSTEM
A fuel oil having the following characteristics should be used for preservation of the fuel system.
Viscosity:
Should not be greater than 22 centistokes at the lowest ambient
temperature expected upon restarting.
Pour Point: Must be at least 150 (-10°C) lower than the lowest ambient temperature
expected upon restarting and should be lower than the lowest
temperature likely to be encountered during the storage period.
Example:
Shell Fusus "A" or equivalent. In the event an oil of this type is not
available, use clean, new #1 diesel fuel to prevent waxing at low
temperatures.
PREPARING THE ENGINE FOR OPERATION
When the engine is to be returned to operating condition, the following procedure must be followed:
1.
Thoroughly clean all external parts and reinstall the sea water pump impeller (if removed).
2.
Remove tape from the fuel tank vent (or filler cap).
3.
Drain fuel tank to remove any remaining oil and condensed water and refill the tank with fuel oil. If tanks have been
filled in lieu of draining, drain the water from the trap (if provided by the boat builder).
4.
Install new fuel filter element and vent the filter (see page 46).
5.
Vent and prime the fuel injection pump (see page 46).
6.
Close all coolant drain taps and fill the system with clean coolant. Check for leaks. If a 4.108 marine engine is
installed with the front of the engine lower than the rear of the engine (this is note recommended installation), it is
possible for an air lock to develop when the cooling system is refilled. To prevent this, loosen the plugs on top of
the manifold and cylinder head so that the air can escape during the refilling operation.
7.
Rotate fresh water coolant pump by hand to ensure freedom of the water pump seals. If the pump will not rotate
with a reasonable amount of force, it will have to be removed to determine the cause of the restriction.
8.
Reinstall water pump drive belt (s).
9.
Remove the rocker cover (s), lubricate rocker assembly (s) with engine oil, and replace cover (s).
10.
Remove tape from the air intake (s), clean filter (s), reinstall the air cleaner (s), and any removed intake pipe.
11.
Remove tape from the exhaust manifold port and reinstall the exhaust pipe (s).
12.
STARTER AND ALTERNATOR Wipe the petroleum jelly from the terminals and check that all connections are
secure.
13.
Connect the battery (s)
14.
Check the level and condition of the lub oil in the oil pan. Change the oil if necessary. Attend to the oil level in the
in-line fuel injection pump (see page 48).
15.
Open raw water seacocks.
16.
Start the engine in the normal manner and check for sufficient oil pressure and battery charge. While the engine is
reaching its normal operating temperature, check for water and oil leaks.
NOTE:
If the foregoing instructions are observed, the storage and return to operation should be efficient and without
any adverse effect on the engine. However, Perkins Engines cannot accept liability for direct or consequential
damage that might arise following periods of storage.
