Walk-Around Inspection
Inspect Engine for leaks and Loose Connections
A walk-around inspection should only tale 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 electrical and mechanical connections, and trash build-up. Remove trash build-up and make repairs as needed.Keep a close watch for leaks. If leaking is observed, find the source and correct the leak. If leaking is suspected, check the fluid levels more frequently than the recommended maintenance intervals and continue to monitor fluid levels until any leak is found and fixed.* Wipe all fittings, caps and plugs before servicing to reduce the chance of system contamination. Inspect:* Radiator and ATAAC cores for leaks and trash build-up.* Radiator and ATAAC air intake system hoses and elbows for cracks and loose clamps.* 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 belt could cause it to break. Inspect:* Water pump for coolant leaks at weep hole. Check the weep hole for water pump breather filter blockage. Replace the filter if necessary. The water pump seal is lubricated by coolant. 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. If excessive leakage occurs, check the coolant level frequently and continue to monitor the level until they water pump is repaired. Inspect:* Lube system components (such as front and rear crankshaft seals, oil pan, oil filters and valve covers) for leaks.* Fuel system for leaks, loose fuel line clamps an fittings and loose or worn hoses.* Air intake system hoses and elbows for cracks and loose clamps.* Engine wiring and electronic wiring harnesses for loose connections and worn or frayed wires.* Engine electrical grounding system for good connections and condition.* Machine guards- all guards must be in place. Repair or replace missing or damaged guards.* Batteries and the level of electrolyte, unless equipped with a maintenance free battery. Disconnect any battery chargers that are not protected against current drain. Refer to the OEM recommendations for battery maintenance.* Gauges, control panel, and generator (if equipped). Observe gauge readings frequently and keep a log of gauge readings. Check for loose or damaged components, and make repairs as needed.* Air service indicator. Service the air cleaner element if the yellow diaphragm enters
