AFTERCOOLER GP-TREATED WATER 1077197 - Caterpillar

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
Engine Storage
Note: If long-term storage for time exceeding 1 year is necessary, contact your local Caterpillar Dealer for the preferred procedure to use in your specific case.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 one month, a complete protection procedure is recommended.For more detailed information on engine storage, see Special Instruction, SEHS9031, "Storage Procedure for Caterpillar Products".Generator Storage
A storage period in excess of six months should be preceded by the following preparation:
Install desiccant bags inside the exciter's cover and install desiccant bags inside the screen of the fan.
Seal the unit in a covering of plastic or other material that has been designed for that purpose.
Adequately tag the generator. This will ensure that preservative greases and desiccant bags are removed before the generator is placed in operation.Bearing Inspection
Ball bearing generators use grease. This grease is subject to deterioration. If the generator is stored more than one year, new ball bearings may be required. These bearings should be greased prior to being put into operation. If inspection indicates that bearings are free of rust or corrosion, and no noise or excessive vibration appear on start-up, replacement is not necessary.Electrical Measurements
Measure the insulation resistance of each winding if the generator was exposed to the following conditions:
Rapid changes in temperature
Freezing
Wet climate during storageNote: These tests should be conducted prior to any power connections that are being made. These tests should be conducted prior to any control connections that are made.Refer to the Generator Maintenance section of this manual to measure the following items:
Exciter Field (Stator)
Exciter Armature (Rotor)
Generator Field (Rotor)
Generator Armature (Stator)For additional information on generator storage, consult your Caterpillar dealer for assistance.
