Engine Preservation 8.1 Preservation Remove anti-corrosion agent from grooves in V-belt pulleys. Install V-belt, retension after brief opera- tion if necessary (see 6.5). Remove covers from intake port and ex- haust ports. 8.1 Preservation 8.1.1 Preserve engine 8.1.2 Remove engine preservation Commission engine. Clean engine (with cold cleansing agent if preferred) using high pressure equipment (see 6.8.1). Run engine until warm, then turn off. Drain engine oil, (see 6.1.2), and fill with anti-corrosion oil. If necessary, clean oil bath 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. Allow the engine to run for approx. 10 mins. Switch off the engine. Turn engine over manually several times to preserve the cylinders and combustion chamber. When turning over with starter, set shut- off lever to stop position. Remove V-belts and store wrapped, dry and recumbent. Spray grooves on V-belt pulleys with anti- corrosion spray. Close off intake ports and exhaust ports, possibly with plugs. If the engine is to remain idle for an extended period of time, it is necessary to take protec- tive measures to prevent the formation of corrosion.
The preservative measures de- scribed here will protect the engine for up to approx. 6 months. The procedure will have to be reversed before the engine is recommissioned Recommended cleaning agent to remove preservatives: - Petroleum benzine (hazardous materials class A3) Anti-corrosion oils to specification: - MIL-L 21260B - TL 9150-037/2 - Nato Code C 640 / 642 © 2001 8
