GEAR (106 teeth) 2P4702 - 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 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. See this Operation and Maintenance Manual, "Refill Capacities and Recommendations" (Maintenance Section).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 1 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".Generator Storage
Store the generator set in a dry area to minimize condensation on the windings. Use space heaters to keep the windings dry, when possible. Wrap the genset in plastic with bags of desiccant for extended storage. Test the insulation of the generator when the generator is removed from storage. Refer to this Special Instruction, SEHS9124, "Winding Insulation Maintenance and Cleaning and Drying of the Generators - "Insulation Resistance Tests"". Dry the generator if the insulation is not acceptable. Refer to this Special Instruction, SEHS9124, "Winding Insulation Maintenance and Cleaning and Drying of the Generators - "Drying"".
