Air Pilot Valve Cartridge Replacement (Pump Revisions A

−

C)

NOTE:

The air pilot valves on pump revisions A through C consisted of an

actuator cartridge and a valve cartridge. One valve set is installed in each

cylinder head. Use this procedure to replace the cartridges. For air motors

without cartridges, refer to the procedure on the following page.

See Figure C 1-3.

1. Remove the screws (4) and flat washers (5) securing the actuator and

valve cartridges (6 and 10) in the cylinder heads.

2. Remove the valve cartridges, then the actuator cartridges. Use pliers if

necessary. Do not damage the housings.

3. Lubricate the external O-rings of the new cartridges with PTFE grease.
4. Install the actuator cartridges into the cylinder heads with the holes in

the flats facing toward the valve cartridge bores.

5. Push the valve cartridges into the air cylinder heads.

NOTE:

You may need to lightly tap on the cartridges with a soft mallet to

engage the O-rings. When installed correctly the flat ends of the valve

cartridges are flush against the actuator cartridges flats and the valve

balls (10A) poke through the holes in the flats to contact the actuator

plungers (6A).
6. Re-install the screws and flat washers to secure the cartridges.
7. Make sure the plastic caps (7) are installed on the actuator cartridge

heads to prevent debris from entering the cartridge.
