If the engine will not be started for several weeks, the lubricating oil will drain from the cylinder walls and from the piston rings. Rust can form on the cylinder liner surface. Rust on the cylinder liner surface will cause increased engine wear and a reduction in engine service life.To help prevent excessive engine wear, use the following guidelines:
Complete all the lubrication recommendations that are listed in this Operation and Maintenance Manual, "Maintenance Interval Schedule" (Maintenance Section).
If freezing temperatures are expected, check the cooling system for adequate protection against freezing. Refer to Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations", "General Coolant Information".If an engine is out of operation and if use of the engine is not planned, special precautions should be made. If the engine will be stored for more than one month, a complete protection procedure is recommended.Storage - Greater than 7 Days and less than 30 Days
Caterpillar recommends maintaining the temperature of the engine to a temperature of at least 5° C (9° F) above ambient temperature to prevent corrosion. The usage of jacket water heaters is an appropriate method.Storage - Greater than 30 Days and less than 1 Year
