If the engine is not started for several weeks, the
lubricating oil drains from the cylinder walls and piston
rings. This lack of oil permits the piston rings to rust;
and causes metal-to-metal contact between the piston
rings, the pistons and the cylinder liners when the engine
is started. This metal-to-metal contact will result in
shorter engine life. To prevent excessive engine wear:
1. Be sure all lubrication points listed in the "Lubrication
and Maintenance Chart" are serviced.
2. Once a week, start and run the engine until it is
automatic start-stop systems, an engine exerciser can
be installed for this purpose.
3. Stop the engine, perform required servicing.
4. If freezing temperatures can be expected, check the
cooling system for adequate protection against freezing.
A 50-50 solution of permanent type antifreeze and
approved water will give protection below -29°C (-200F).
If it will be impossible to start the engine every week,
see your Caterpillar dealer for instructions to prepare
your engine for extended storage.
