Air Compressor
Inspect/Rebuild or Exchange
Do not disconnect the air line from the air compressor governor without purging the air brake and auxiliary air systems.Failure to purge the air brake and auxiliary air systems before removing the air compressor and/or air lines could cause personal injury.
Inspect the air compressor as instructed by the truck/vehicle manufacturers' instructions or for more information on how to check your air compressor, refer to the Service Manual for this engine.If you decide to inspect your air compressor, be sure to observe the following actions.* Release the air pressure in the air tank until the air pressure is zero.* Visually check for fluid leaks and listen for air leaks.* Remove discharge fittings and inspect compressor discharge port and discharge line for excessive carbon deposits. The discharge line must be cleaned or replaced and the compressor checked more thoroughly if there is excessive carbon build-up in either the discharge line or compressor discharge port.For more information on how to check your air compressor, refer to the Engine Service Manual.
DO NOT store alcohol in the cab. Alcohol is highly flammable and toxic.
In arctic conditions, use alcohol injection to prevent moisture from freezing in the air system.Removal and Installation
Refer to the established procedure in the Service Manual to Remove and Install the Air Compressor, or contact Caterpillar for assistance.Water Pump
Inspect/Replace
* Inspect the water pump for 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.Check for unusual noise and/or wobbling of the pulley bearings.Removal and Installation
If the assembly should require disassembly, refer to the established procedure in the Service Manual to Remove and Install the Water Pump, or contact Caterpillar for assistance.Fan Drive & Water Pump Belt Tightener Assembly
Inspect/Check Fan Drive
