In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 9% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.

ACTION REQUIRED

Show/hide table

Inspect the air compressor head gasket to determine if a paper or metal head gasket is currently installed on the air compressor.

No air compressor head gasket replacement is necessary if inspection results determine a metal head gasket is currently in use.

If inspection results determine a paper gasket is currently installed, refer to REHS3795 for Rework Procedure.

Please read following warning.

WARNING
When working on air system components the following precautions should be observed:
1. Stop engine when working under a vehicle. Always block the vehicle wheels to prevent a fore or aft roll. Bleeding off system pressure may cause the vehicle to roll. Keep hands away from brake chamber push rods and brake adjusters; they may apply as air system pressure drops.
2. Never connect or disconnect a hose or line containing air pressure. It may whip as air escapes. Never remove a component or a pipe plug unless you are certain all system air pressure has been exhausted.
3. Never exceed recommended working air pressure and always wear safety glasses when working with air pressure. Never look directly into component ports or direct a pressurized air flow at anyone.
4. Never attempt to disassemble a component until you have read and understood all recommended procedures. Some components contain powerful springs and injury can result if not properly disassembled. Use only proper tools and observe all precautions pertaining to the use of those tools.
