8.1 Preservation
If the engine is to remain idle for an extended
period of time, it is necessary to take protective
measures to prevent rust formation. The pre-
servative measures described here will protect the
engine for up to 6 months. The procedure will
have to be reversed before the engine is re-
commissioned.
● Anti-corrosion oils to specification:
– MIL-L-21260B
– TL 9150-037/2
– NATO code C 640/642
● Recommended cleansing agent to remove
preservatives when recommissioning engine:
– Petroleum benzine (hazardous materials
class A3)
Preserving Engine:
● Clean engine (with cold cleansing agent if
preferred). See 6.3.2.
● Run engine until warm, then turn off.
● Drain engine oil (see 6.1.2) and fill with anti-
corrosion oil.
● Drain coolant (see 6.3.3/6.3.5).
● Fill with anti-corrosion agent (see 4.3.3).
● If necessary, clean oil bath air cleaner (see 6.4.3)
and fill with anti-corrosion oil.
● Drain fuel tank.
● Make up a mixture of 90% diesel fuel and 10%
anti-corrosion oil, and refill fuel tank.
● Run engine for about 10 minutes.
● Turn engine off.
● Turn engine over manually several times. If
using starter, set shutdown lever to stop position.
● Remove V-belts 1 and store in wrapped condition.
● Spray grooves of V-belt pulleys 2 with anti-
corrosion agent.
● Close off intake ports 3 and exhaust ports 4.
● Lightly grease and replace coolant filler 5.
● Drain anti-corrosion agent (see 6.3.3 / 6.3.5).
Removing Engine Preservatives:
● Remove anti-corrosion agent from grooves in
V-belt pulleys 2.
● Install V-belts 1. Retension after brief operation
is necessary (see 6.5).
● Remove covers from intake port 3 and exhaust
