Preservation Procedure

a) Using H.S.D. fuel, run the engine at approximately 70% of maximum rated speed with 'No' load for 5
minutes to warm up the engine (in case of fixed speed engines like engine for Genset, it can be run
at rated speed).
b) After stopping the engine, drain lube oil from sump and refill with suitable preservative oil as mentioned
above.
c) Run the engine on 'No' load for 3 minutes. During this time the preservative will be circulated throughout
the lube oil system of engine. Stop the engine and disconnect diesel fuel supply to fuel pump inlet.
For engine speed refer point 8.2 (a).
d) Prepare a solution Diesel + Preservative Oil (5:1 ratio) in a separate tank and connect fuel line from
this tank, directly to fuel pump inlet ensuring gravity feed (by-pass fuel filter).
e) Drain coolant from cooling system and thoroughly flush with clean water. The system then should be
filled with mixture of water and any of the cooling system preservatives mentioned in Annexure-1.
f) Electrically crank the engine tilt it fires ( in case of purely hand start engine, hand - crank the engine
using decompressor lever, till it fires) and let it run for 30 seconds. During this time the diesel in fuel
pump gallery and high pressure pipes will be displaced by Diesel + Preservative Oil mixture. Stop the
engine.

Engine speed during above running -

• In case of variable speed engine - 800 to 1000 rpm
• In case of fixed speed engine - Rated speed at 'No' load. (Genset, Pumpset etc.)
g) Close the air inlet manifold (for the air cleaner inlet) and crank the engine by starter for 5 to 10
seconds. (In case of purely hand start engine, it should be hand cranked using the de-compressor
lever). This will ensure coating of Diesel + Preservative oil on the combustion chamber surfaces.
h) Drain preservative oil from oil sump, reinstall drain plugs and reconnect fuel filter into the fuel pipe
line.
i) Treat all unpainted external ferrous metal parts with two coats of suitable rust preventer as recommended
in 8.1, allowing sufficient time for the first coat to thoroughly dry before applying second coat.
