FILTER-OIL 1232873 - Caterpillar

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, which will increase engine wear which can reduce engine service life.To help prevent excessive engine wear, use the following guidelines:
Complete all of the lubrication recommendations that are listed in Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations".
If freezing temperatures are expected, check the coolant for protection against freezing. The cooling system must be protected against freezing to the lowest expected outside temperature. See Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations". Add the proper coolant/water mixture, if necessary.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.Your Caterpillar dealer will have instructions for preparing the engine for extended storage periods.For more detailed information on engine storage, see Special Instruction, SEHS9031, "Storage Procedure for Caterpillar Products".
