MAINTENANCE OF ENGINE LAID UP FOR LONG PERIOD
For engines which are not likely to be operated
for a long period the following maintenance
operations are recommended to prevent
deterioration :
1. Add 1% of water soluble anticorrosion oil to
the cooling water in the radiator. Then run the
engine until it is warm-water temperature
should reach at least 60
0
C, so that the
anticorrosion oil is distributed throughout the
cooling system. Then drain cooling water
completely.
2. For preserving the fuel system 5 to 10% of
engine anticorrosion oil has to be added to
the fuel in the fuel tank as well as to the
oil in the housing of the injection pump. Then
operate the engine for a few minutes. The
above fuel mixture provides sufficient
protection against corrosion even if the
injection pump is not operated for a long
period of time. Then remove pump cover and
spray pump elements and springs with engine
oil containing 5 to 10% of anticorrosion oil.
Screw on pump cover and spray outside of
the pump with the mixture.
3. To preserve the engine, drain engine oil while
it is hot and replace by recommended
anticorrosion oil. Then crank the engine for
5 seconds with the starter motor.
4. For the protection of the cylinder walls
remove the nozzles and inject 20 cc of
anticorrosion engine oil into each cylinder.
When doing so, the piston should be at the
bottom dead centre. Refit nozzle and crank
the engine with the starter motor for about 5
seconds. Before doing so, disconnect injection
lines from the injection pump, so that
5. Spray the unpainted parts of the engine with
anticorrosion oil Rustban 339 compound.
Cover the fan belt and rubber hoses before
doing so.
After the cylinder head cover has been
removed and the inlet ports closed, the rocker
arms, valves etc. should be sprayed with engine
anticorrosion oil and the cover refitted.
6. Batteries, which are not used, should be
serviced at regular intervals, in order to keep
them in good condition. Batteries should be
stored in a cool and dry room. Check battery
condition every fortnight and if necessary
recharge.
8. Cover up opening for air cleaner, exhaust pipe
and engine breather pipe. The parking area
should be airy and dry.
PREPARATION OF ENGINE AFTER EXTENDED
STORAGE PERIOD
i . a . Check engine oil level, top up, if
necessary.
b. Remove injectors and check for spray
and nozzle opening pressure.
ii .Hold injection pump control lever in "stop'
position.
iii. a. Crank the engine with the help of starter
until oil pressure is indicated on the
gauge. Do not depress accelerator pedal.
Cranking interval should be long enough
to allow for battery recoveries.
b. Refit injectors.
iv. Finally start engine in the usual manner.
v. The initial operation oil (running-in-oil) may
remain in the engine for a short period of
time (not more than 25 hrs.) after termination
of the storage period. However, the oil should
be drained as soon as possible and replaced
by HD oil grade in accordance with the
ambient temperature conditions.
