You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.This maintenance is to be performed at the fuel interval specified in the Maintenance Schedule. Before proceeding with this maintenance, perform all previous maintenance interval requirements.Air Compressor (If Equipped)
Inspect/Rebuild or Exchange
Caterpillar recommends that the most cost effective method of operation and maintenance for the air compressor is to inspect the unit before it fails and make the decision to rebuild or exchange.By maintaining the air compressor before failure, unscheduled downtime and potential damage to other engine parts are reduced. The prevention of unscheduled downtime saves money and lowers operating costs.
Do not disconnect the air line from the air compressor governor without purging the air and/or auxiliary air systems.Failure to purge the air systems before you remove the air compressor could cause personal injury.
Inspect the air compressor as instructed by the 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. Visually check for fluid leaks and listen for air leaks. Release the air pressure in the air tank until the air pressure is zero.If the engine is operated until the air compressor fails, it could cause additional damage to the engine. A failed air compressor could contaminate the engine oil with particles of materials since engine oil also lubricates the air compressor. The circulation of these contaminates through the engine lubricating system could damage the engine's main and connecting rod bearings.Visually check for fluid 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.
DO NOT store alcohol (for cold weather operation) in the operator area. Alcohol is highly flammable and toxic.
In arctic conditions, use alcohol injection to prevent moisture from freezing in the air system.For more information on how to check your air compressor, refer to the manufacturer's instructions or engine Service Manual. For more information on Maintenance Options, refer to Terminology topic in this Manual.Caterpillar Recommendation
The most cost effective repair option is to rebuild the air compressor with a repair kit that can be obtained from your Caterpillar dealer. To minimize downtime, Caterpillar recommends that the use of Remanufactured components (subject to availability) as a cost effective option.Removal and Installation
Refer to the established procedure in the Service Manual for this engine to Remove and Install these components or contact your Caterpillar dealer for assistance.Electric Starting Motor (If Equipped)
Inspect/Rebuild or Exchange
One unscheduled failure caused by your electric starting motor will cost more in downtime than servicing your starting motor before failure.If you service your electric starting motor before failure, you will minimize unscheduled downtime. The prevention of unscheduled downtime saves you money and lowers
