Air Motor

NOTE: 

For easier reassembly, start with the top cover 

(210) turned over on the workbench and assemble the 
air motor upside-down.

1. Lubricate and install the o-ring (402) on the top 

cover (410).

2. Lubricate the inside of the cylinder (405). Lower the 

cylinder onto the top cover (410).

3. Install the shield (406) around the cylinder (405) and 

in the groove on the top cover (410).

4. See F

IG

. 13. Lubricate and install new u-cup seal 

(407) in the bottom of the bearing in the bottom 
cover (401). The lips must face down. Lubricate and 
install new u-cup seal (407) in the top of the bearing. 
Lips must face up. Install retaining ring (417).

5. Lubricate and install the o-ring (402) on the bottom 

cover (401). 

6. Carefully push the threaded end of the rod (418) up 

through the bottom cover (401).

7. Apply 16G561 adhesive to the threads of the rod 

(418). Screw the piston (419) onto the rod. Place 
the piston in a vise with soft jaws and torque to 
35-40 ft-lb (47-54 N•m).

8. Lubricate and install the o-ring (404) on the piston 

(419). 

9. See F

IG

. 14. Carefully place the bottom cover/piston 

assembly on the cylinder (405), sliding the piston 
(419) into the cylinder. The manifold surfaces of the 
top and bottom covers must align. Be sure the 

shield (406) is in the groove on both the top and bot-
tom covers.

10. Install the tie bolts (412) hand tight.

11. Install two gaskets (408) on the manifold (420). 

Install the manifold (420). Torque screws (411) to 
95-105 in-lb (10.7-11.9 N•m).

NOTE: 

The manifold is reversible for ease of placement 

of muffler or remote exhaust.

12. Align the air valve gasket (409) on the manifold, 

then attach the air valve (414). Torque screws (411) 
to 95-105 in-lb (11-12 N•m).

13. Tighten the tie bolts (412) halfway. Work in a criss-

cross pattern. Check that the shield (406) remains in 
the grooves on both covers. Continue tightening the 
bolts in pattern to 11-13 ft-lb (15-18 N•m).

14.

On 3.5 in. motors only,

 lubricate the o-ring (430). 

Install it and the plug (431) in the top cover (410).

15. Lubricate and install pilot valves (413) in top and 

bottom cover. Torque to 95-105 in-lb (11-12 N•m).
