GEAR-YM 3783970 - Caterpillar

Inspect the Generator Set for Leaks and for Loose Connections
A walk-around inspection should only take a few minutes. When the time is taken to perform these checks, costly repairs and accidents can be avoided.For maximum engine service life, make a thorough inspection of the engine before starting. Look for items such as oil leaks or coolant leaks, loose bolts, worn belts, loose connections, and trash buildup. Make repairs, as needed:
The guards must be in the proper place. Repair damaged guards or replace missing guards.
Ensure that the areas around the rotating parts are clear.
Wipe all caps and plugs before the engine is serviced in order to reduce the chance of system contamination.
For any type of leak (coolant, lube, or fuel) clean up the fluid. If leaking is observed, find the source and correct the leak. If leaking is suspected, check the fluid levels more often than recommended until the leak is found or fixed, or until the suspicion of a leak is proved to be unwarranted.
Accumulated grease and/or oil on an engine or deck is a fire hazard. Remove this debris with steam cleaning or high pressure water.
Air Inlet and Exhaust System
Inspect the piping for the air inlet and exhaust system and the elbows for cracks.
Ensure that the air filters are in place.
Ensure that all clamps and connections are secure.
Observe the air cleaner service indicator. Service the air cleaner when the yellow diaphragm enters the red zone, or when the red piston locks in the visible position.Cooling System
Inspect the cooling system for leaks or loose connections.
Inspect the cooling system hoses for cracks and for loose clamps.
Inspect the water pumps for evidence of leaks.
Inspect the fan drive belts for cracks and for deterioration.
Check the coolant level. Add coolant, if necessary. For information on the proper coolant to use, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations".Note: The water pump seal is lubricated by coolant in the cooling system. As the engine cools down, and the parts contract, a small amount of leakage may occur.Excessive coolant leakage may indicate the need to replace the water pump seal. For the removal of the water pump and the installation of the water pump and/or seals, refer to the Service Manual for the engine or consult your Cat dealer.Driven Equipment
Perform any maintenance that is required for the driven equipment. Refer to the Operation and Maintenance Manual for the generator.
Ensure that the main circuit breaker is open.Electrical System
Inspect the wiring for the following conditions:
Loose connections
Wiring that is worn or frayed
Inspect the ground strap for a good connection and for good condition.
Inspect the engine-to-frame ground strap for a good connection and for good condition.Fuel System
The high-pressure fuel system is sensitive to debris. The debris can lead to early erosion and replacement for many of the high-pressure fuel system components and lack of performance. Caution should be taken by covering any fuel system opening during maintenance with a CLEAN cover. Refer to Special Instruction, SEBF9107, "CR1100 Fuel System Flushing Procedure" and Special Instruction, SEBF9109, "CR1100
