Air Compressor

The air compressor incorporates three of the major systems of a diesel engine (air, lubrication, and coolant). Proper inspection of the air compressor includes inspecting for air, oil, and coolant leaks. A failed air compressor can create inadequate internal sealing resulting in excessive crankcase pressure, or allowing an engine to ingest oil. The air compressor should be inspected per the maintenance intervals, Preventive Maintenance Tables.
