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 should only take a few minutes of your time. By taking the time to make these checks, costly repairs and accidents can be avoided and your equipment will be ready to run should the need arise.For maximum engine service life, make a thorough inspection of the engine compartment before starting the engine. Look for items such as oil or coolant leaks, loose bolts, worn fan belts, loose connections and trash build-up. Remove trash build-up and have repairs made as needed.* All guards must be in place. Repair or replace missing or damaged guards.* Wipe all fittings, caps and plugs before servicing 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 oil on an engine or deck is a fire hazard. Remove this debris with steam cleaning or high pressure water.
* Make sure cooling lines are properly clamped and tight. Check for loose fittings or leaks. Check the condition of all pipes and fittings.* Check the marine transmission oil level. Refer to the marine transmission OEM literature or refer to the vessel OEM literature.* Inspect water pump(s) 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.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 the lube system for leaks at the front and rear crankshaft seals, the oil pan, the oil filters, and the valve covers.
Fuel line clamps should not be over torqued. Over torqueing causes the clamps to butterfly, which results in low clamping force, fuel line vibration and eventual failure. Refer to the Torque Specifications in this manual.
* Inspect the fuel system for leaks. Look for loose fuel line clamps and fittings and loose or worn hoses.* Inspect the air inlet system piping and elbows for cracks and loose clamps.* Inspect the fan belt and the accessory drive belts for cracks, breaks or other damage. Belts for multiple groove pulleys must be replaced as matched sets. If only one belt of a two or three belt set is replaced, it will carry more of a load than the belts not replaced since the older belts are stretched. The additional load on the new belt could cause it to break.* Drain water and sediment from fuel tanks on
