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, lip-first, into the housing. 5. Push the housing (26) and seal (22) over the shaft (3) and up against the bearing housing. 6. Apply Loctite Primer N7649 and Loctite TL242, 243, or equivalent (“blue” Loctite) to the fluid housing screws (23) and loosely install the screws to retain the housings. Do not tighten the screws yet. 7. Insert the gasket (38) and seat (25). These items are reversible and can be installed in either direction. 8. Apply Loctite Primer N7649 and Loctite TL242, 243, or equivalent (“blue” Loctite) to needle (27) and tighten to 15–20 in–lb (1.7–2.2 Nm). 9. Apply air pressure to the CLOSE port, or to the pneumatic trigger valve if installed. This will align the shaft, seal, and bearing. Tighten the fluid housing screws (23) oppositely and evenly to 40–45 in-lbs (4.5–5 Nm). 10. Install the nosepiece (40) with the PTFE o-ring (39), screw (15), and snuff-back ring (41), if used. The snuff-back ring has an internal bevel on one end which faces into the nosepiece. Tighten the nosepiece screws to 15–20 in-lbs (1.7–2.2 Nm). 20 308876 Parts (Models 243482 and 243666 only) 2222222 34 12 13, 14 6 75 4 3 28, 2920212239 27 23 1 4 40 45 2 9 1030 191816 26 3825 2 2 2 2 Tighten oppositely and evenly to 40–45 in-lbs (4.5–5 Nm). 2 Lubricate with grease supplied in the repair kit. 1 1540 Model 243482 3 Tighten to 15–20 in lbs (17–22 Nm) 4 Apply Loctite Primer N7649 and Loctite TL242, 243, or equivalent (“blue” Loctite).
