Disassembly 1. Relieve all air and fluid pressure. 2. Disconnect the valve from the system. 3. Remove the four nosepiece screws (15), and pull the nosepiece (40) away from the valve. Remove the snuff-back ring (41). See Fig. 5, page 14. 4. Use an 1/8 in. pin punch in the needle hole (A) to unscrew the needle (27). If the shaft (3) spins, insert a dowel pin in the shaft hole (B) to hold it steady, then unscrew the needle (27). 5. Remove the seat (25), gasket (38), and o-ring (39). 6. Remove the two fluid housing screws (23) and remove the fluid housing (26). Remove the primary fluid seal (22) from the fluid housing (26). 7. Pull the bearing/lube housing (19) from the air cylinder (1). Remove the bearing (21), bearing o-ring (16), and secondary fluid seal (20). Remove the grease fittings (18). 8. Remove the C-clip (12) from the back of the air cylinder (1). Push the shaft (3) into the air cylinder to dislodge the air cylinder cap (11). Remove the cap o-ring. 9. Remove the internal C-clip (12). Push the shaft (3) to dislodge the piston (10) assembly from the air cylinder (1). 10. Remove the pin (7), o-ring (9), and piston o-ring (6). 11.

Lubricate the shaft o-rings (4) and the bearings (5) with grease supplied in the repair kit. Insert o-rings into the air cylinder (1) and air cap (11) cavities. See Fig. 5. 2. Press the bearings (5) flush into the air cylinder housing and air cap, trapping the o-rings (4). 3. Lubricate and reassemble the piston assembly; piston (10), o-ring (9), dowel pin (7), o-ring (6), and shaft (3). Tighten the jam nut (45) to 15–20 in-lb (1.7–2.2 Nm). The shaft (3) should hang with some play to be self-aligning in the bearing. 4. Lubricate the air cylinder (1) ID with the grease supplied. Push the piston (10) assembly into the air cylinder. 5. Orient the air inlet manifold (2) (if used) as shown. Match the gasket openings to the air ports. Fluid Section 1. Lubricate the bearing (21), o-ring (16) and cup seal (20). Put the o-ring (16) on the bearing. Carefully insert the seal (20) into the bearing recess, with the lips of the o-ring facing into the bearing. Be careful not to damage the seal lips. 2. Push the bearing (21) seal end first into the housing (19). Be sure that the grease hole in the side of the bearing lines up with the grease ports in the housing (19). 3. Holding the bearing (21) in place, push the bearing assembly over the shaft (3). 4. Lubricate the main fluid seal (22) and its cavity in the housing (26). Carefully press the seal, li...
