You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.Walk-Around Inspection
Inspect Engine for Leaks and Loose Connections
A walk-around inspection is recommended to ensure the installation is clean and leaks are kept to a minimum. This should only take a few minutes and by taking the time to make these checks, costly repairs and accidents can be avoided and the equipment will be ready to run should the need arise.For maximum service life of your engine(s), make a thorough inspection before starting the engine. Look for such items as oil or coolant leaks, loose bolts, worn belts, loose connections and trash build-up. Remove trash build-up and have repairs made as needed.
Accumulated grease and oil on an engine or deck is a fire hazard. Remove this debris with steam cleaning or high pressure water, Every 3 Month interval or 72 500 km (45,000 miles), or each time any significant quantity of fluid is spilled on an engine or deck.
Check the fluid levels more frequently than the recommended maintenance intervals and continue to monitor fluid levels until any leak is found and fixed. If leaking is observed, find the source and correct the leak. If leaking is suspected, check the fluid levels more frequently than the recommended intervals.* Wipe all fittings, caps and plugs before performing maintenance to reduce the chance of system contamination. Inspect:* Cooling system lines and air intake system hoses, piping and elbows for cracks and loose clamps. Check the condition of all pipes and fittings.* Water pumps for coolant leaks. The water pump seal is lubricated by coolant in the cooling system. It is normal for a small amount of leakage to occur as the engine cools down and parts contract. If leaks are found, check the coolant level frequently and continue to monitor the level until the water pump is repaired. Excessive coolant leakage may indicate the need to replace the water pump seal.For removal and installation of water pumps and/or seals, see the Service Manual for this engine or consult your Caterpillar dealer. Inspect: * Lube system for oil leaks, such as front and rear crankshaft seals, oil pan, oil filters and valve covers.* Fuel system for leaks, loose fuel line clamps and fittings, and loose or worn hoses. Inspect:* Wiring and wiring harnesses for loose connections and worn or frayed wires.Check condition of gauges. Replace if cracked or cannot be calibrated.While operating, frequently observe the engine oil pressure, oil filter differential, fuel pressure, fuel filter differential, water temperature and the air cleaner differential gauges.All guards must be in place. Repair or replace missing or damaged guards.Check condition of batteries and the level of electrolyte, unless equipped with a maintenance free battery.Refer to OEM or locomotive manufacturers' recommendations for battery maintenance.* Check the air system pressure. Adjust if necessary. Fill all air system lubricators.Refer to OEM or locomotive manufacturer's recommendations.Check Fluid Levels
