RECEPTACLE AS 2906516 - Caterpillar

If the engine is not started for several weeks, the lubricating oil will drain from the cylinder walls and piston rings. Rust will form on the cylinder liner surface, which will increase engine wear and result in shorter engine life.To prevent excessive engine wear:1. Be sure all lubrication points mentioned in the Lubrication and Maintenance Intervals chart are serviced.2. If freezing temperatures can be expected, check the cooling system for adequate protection against freezing. A 50-50 solution of Caterpillar permanent-type antifreeze and approved water will give protection below -29°C (-20°F).If it will be impossible to start the engine every week, consult your Caterpillar dealer for instructions to prepare your engine for longer storage periods. For extended engine storage, refer to Special Instruction, Form SEHS7392.
