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.

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.
