CYLINDER GP-BOOM 1559068 - Caterpillar

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 mentioned in the LUBRICATION AND MAINTENANCE CHART are serviced.2. Once a week, start and run the engine until it is thoroughly warm. For unattended automatic start-stop systems, an engine exerciser can be installed for this purpose.3. Check the cooling system for adequate protection against freezing if freezing temperatures can be expected.If it will be impossible to start the engine every week, see you Caterpillar dealer for instructions to prepare your engine for further storage.
