Preventive Maintenance Intervals

Inspect the entire air system for leaks daily. Look especially for torn air inlet piping

or boots and loose or damaged clamps. Have worn or damaged parts repaired or

replaced, as required. Retighten loose connections

Air Cleaner Replacement - Dry type air cleaner elements should be replaced after

one year of service or when the maximum allowable air intake restriction has been

reached, whichever comes first.

Air-to-Air Charge Cooler - Periodically inspect the air-to-air charge cooler for

buildup of dirt, mud, etc. and wash off using a mild soap solution. Check the charge

cooler, ductwork, and flexible connections for leaks and have repaired or replaced,

as required.

Exhaust System

The exhaust manifold retaining bolts and other connections should be inspected for

leaks. The exhaust pipe rain cap should be checked for proper operation, if so

equipped.

Air Compressor

The air compressor incorporates three of the major systems of a diesel engine (air,

lubrication, and coolant). Proper inspection of air compressor would include

inspecting for air, oil, and coolant leaks. Due to inadequate internal sealing air

compressors, when failed, can produce excessive crankcase pressure or allow an

engine to ingest oil.

Vibration Damper

The viscous vibration damper should be inspected periodically and replaced if

dented or leaking. Heat from normal engine operation may, over a period of time,

cause the fluid within the damper to break down and lose its dampening properties.

For this reason the viscous vibration damper must be replaced at time of normal

major engine overhaul, regardless of apparent condition.
