- Clean the filter element by dipping it in alcohol or other
cleaning solvent. Blow compressed air through the filter element (inside
to outside) to loosen surface dirt and to dry the element. If it is
not damaged, the sintered metallic filter element will last the life
of the vehicle.
Wipe out the filter housing with a clean, dry, lint-free rag. Clean and inspect the O-rings and the end cap. Replace any parts that are damaged.
- Install the large O-ring, then the filter element (small end first) into the filter housing.
- Install the small O-ring in the end cap, then install the end cap and tighten it until firm.
- Start the engine, and build pressure in the air system. Check for air leaks at the filter housing and air line connections; repair any leaks.
Warning: Drain the air supply; if the air supply is not drained before the air filter/regulator is serviced, serious injury and component damage could result.
Warning: Wear safety goggles when using compressed air to clean parts, as permanent harm to eyes could result from flying debris.
Note: Do not remove, disassemble, or adjust the air regulator. If the air regulator is not keeping the air pressure between 58 and 63 psi (400 to 435 kPa), replace the air filter/regulator. It cannot be repaired.
Notice: A leaking air filter or air lines can cause slow or hard shifting of the transmission, and eventual transmission damage.
