Inspect the Engine 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, thoroughly inspect the engine room before starting the engine. Look for items such as leaks, loose bolts, loose connections, and trash buildup. Make repairs, as needed.
The guards must be in the proper place. Repair damaged guards or replace missing guards.
Wipe all caps and plugs before the engine is serviced in order to reduce the chance of system contamination.
For any type of leak, 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.
Ensure that cooling lines are properly clamped. Check for leaks. Check the condition of all pipes.
Inspect the water pumps for coolant leaks.Note: The water pump seal is lubricated by coolant in the cooling system. It is normal for a small amount of leakage to occur when the engine cools and the parts contract.Excessive coolant leakage may indicate the need to replace the water pump seal. For instructions on removal and installation of water pumps and/or seals, refer to the Service Manual, "Disassembly and Assembly" module for the engine or consult your Cat dealer.
Inspect the lubrication system for leaks at the front crankshaft seal, the rear crankshaft seal, the oil pan, the oil filters, and the valve covers.
NEVER use a flame to check for gas leaks. Use a gas detector.An open flame can ignite mixtures of air and fuel. This will cause explosion and/or fire which could result in severe personal injury or death.
Check the fuel system for leaks. Look for loose fuel line clamps.
Inspect the piping for the air inlet system and the elbows for cracks and for loose clamps.
Inspect the wiring and the wiring harnesses for loose connections and for worn wires or frayed wires.
Inspect the ground straps for good connections and for good condition.
Inspect the exhaust system for leaks. If a leak is found, make repairs.
