MOTOR GP-PISTON 4871994 - Caterpillar

Engine
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
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 an engine is not used, oil can run off the following parts that normally receive lubrication: cylinder walls, piston rings, main bearings, connecting rod bearings, crankshaft, and gears.This lack of lubricant allows corrosion to begin to appear on the metal. This condition is worse in areas of high humidity.When the engine is started again, metal to metal contact will cause wear before the surfaces receive oil. To minimize this wear, use the starter to turn the engine with the throttle in the FUEL OFF position. When oil pressure is shown on the pressure gauge, start the engine.
Clean the engine of any dirt, rust, grease, and oil. Inspect the exterior. Paint areas that contain paint damage with a good quality paint.
Remove any dirt from all air cleaners. Check all seals, gaskets, and the filter element for damage.
Apply lubricant to all points in this Operation and Maintenance Manual, "Maintenance Interval Schedule".
Drain the crankcase oil. Replace the crankcase oil and change the oil filters. For the proper procedure, refer to this Operation and Maintenance Manual, "Engine Oil and Filter - Change".
If the engine is equipped with an air starting motor, fill the reservoir with a mixture of 50 percent volatile corrosion inhibitor (VCI) and 50 percent engine oil.
Add VCI to the crankcase oil. The volume of VCI in the crankcase oil should be 3 to 4 percent.Note: If the engine crankcase is full, drain enough engine oil so the mixture can be added.
Remove the air filter elements. Turn the engine at cranking speed with the throttle control in FUEL OFF position. Use a sprayer to add a mixture of 50 percent VCI and 50 percent engine oil into the air inlet or turbocharger inlet.Note: VCI oil mixture is also to be added to the inlet by removing a plug for checking boost pressure/temperature at the cylinder head air inlet area. The sprayer should produce a fog to ensure it is drawn into each cylinder. The minimum application rate is 5.5 mL per L (3 oz per 1000 cu in) of engine displacement.
Use a sprayer to apply a mixture of 50 percent VCI and 50 percent crankcase oil into the exhaust openings. The minimum application rate for the oil mixture is 5.5 mL per L (3 oz per 1000 cu in) of engine displacement. Seal the exhaust pipe and seal any drain holes in the muffler.
Remove the fuel from the secondary fuel filter housing. Alternately, empty and reinstall the spin-on fuel filter element to remove any dirt and water. Drain any sleeve metering
