Information:

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 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, lubricant, 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.
* Make sure cooling lines are properly clamped and tight. Check for loose fittings or leaks. Check the condition of all pipes and fittings.* Inspect the water pump for coolant leaks at the weep hole. 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 lubrication system for leaks at the front and rear crankshaft seals, oil pan, oil filters and valve covers.
Fuel line clamps should not be overtightened. Overtightening causes the clamps to fatigue, 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, 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 radiator core for leaks and trash build up. Clean the front of the radiator with a stainless steel brush and soapy water.* Inspect the radiator and cooling system hoses and elbows for cracks and loose clamps. Depending on your findings and operating environment, the maintenance interval for cleaning the radiator can be extended from a Daily to an as needed basis.* Inspect the fan and 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
