11. Carefully place the bottom cover (201) on the cylin-

der (211), sliding the rod (206) through the bearing 
(202). The manifold surfaces of the top and bottom 
covers must align. Be sure the shield (212) is in the 
groove on both the top and bottom covers.

12. Install the tie bolts (210) hand tight.

13. Install two gaskets (214) on the manifold (215), and 

install the manifold. Torque bolts to 95-105 in-lb 
(11-12 N•m). (The manifold is reversible for ease of 
placement of the muffler or the remote exhaust.)

14. Align the pneumatic valve gasket (216) on the mani-

fold (215), then attach the pneumatic valve (217).

15. Tighten the bolts (210) halfway. Work in a 

criss-cross pattern while tightening the tie bolts. 
Check that the shield remains in the grooves on 
both covers. Continue tightening the bolts in pattern 
and torque to 25-30 ft-lb (34-40 N•m).

16. Lubricate and install the pilot valves (219) in the top 

and bottom covers. Torque to 5-105 in-lb (11-12 
N•m).

17. Reinstall the mufflers (18).

18. See 

Reconnect the Pneumatic Motor

 on page 26.

Reconnect the Pneumatic Motor

1.

Replace the motor on the mounting bracket (2).

2.

Screw the tie rods (3) into the motor, with the top 
hex nuts (4) attached. Torque the tie rods to 5-10 
ft-lb (7-13 N•m). 

NOTE:

 Always tighten the tie rods (3) before tightening 

the top hex nuts (4).

3.

Tighten the top hex nuts (4) to secure the mounting 
bracket (2).

4.

Slide the pump with the adapter plate (6) attached 
onto the tie rods (3). 

5.

Install the tie rod nuts (8). Torque to 100 in-lb 
(11 N•m).

6.

Align the hole in the fluid plunger (109) with the hole 
in the pneumatic motor plunger (206).

7.

Slide the drip shield (4) to the top of the tie rods (3) 
and replace the tie rod shield (15).

8.

Reconnect the pneumatic and fluid hoses, and the 
ground wire.
