NUT 5V7610 - Caterpillar

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 service life of the equipment, make a thorough inspection of the installation before starting the engine. Look for items such as oil leaks or coolant leaks, loose bolts, worn belts, loose connections and trash buildup. Make repairs, as needed.
Inspect the engine and the compressor according to the information that is provided by the OEM of the equipment.
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 (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/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 equipment for dirt and debris.Inspecting During Operation
After starting the chiller, listen for excessive noise and/or unusual noise. Inspect the gearbox for oil leaks and for excessive vibration.Monitor the Gauges
During operation, monitor the following parameters:
Aftercooler inlet water temperature
Engine rpm
Gearbox oil temperature
Gearbox oil pressure
Inlet manifold air pressure
Inlet manifold air temperature
Jacket water temperature
Pressure of the air control for the clutchMaintain a log of the data as a permanent record. Compare the new data to the data that was previously recorded. Investigate any significant changes.Check the Gearbox Oil Level

(1) Sight gauge
(2) Cover A sight gauge is mounted on the side of the gearbox. The sight gauge has an upper mark and a lower mark. Observe the oil level in the sight gauge.When the chiller is NOT operating, the oil level should be approximately 2 cm (3/4 inch) above the upper mark.When the chiller IS operating, the oil level should be between the upper mark and the lower mark.Add oil, if necessary. The cover of the gearbox must be removed in order to add oil. If the equipment is operating, stop the operation. Attach a “DO NOT OPERATE” tag or a similar warning tag to the controls. Remove the cover of the gearbox and pour the correct amount of oil into the gearbox. For the correct oil to use, see this Maintenance Manual, "Lubricant Specifications" topic.Inspect the Indicator for the Gearbox Oil Filter
