TABLE 5

15. Position the Friction Facing on top of the piston with

the narrow end of the taper pointing up. Use care to
ensure that the Friction Facing is concentric to the
piston, as this will aid in the installation of the output
shaft in step 16.

16. Support the inner race of the new Ball Bearing (Item

2) and press the Output Shaft (Item 1) into the new
Bearing (Item 2) and Air Chamber (Item 6).

17. Replace the Spring (Item 9) and Input Flange (Item

10).

NOTE: On the Size 2 Spring, one end will be fused. Be
sure that the fused end is down and makes contact with
the facing (Item 8).

18. Apply a drop of Loctite® 242 to the threads of the

Socket Head Cap Screws (Item 11).

19. Reinstall and tighten the four Socket Head Cap

Screws (Item 11), securing the Air Chamber (Item 6)
to the Input Flange (Item 10). Alternate as you tighten
the four Socket Head Cap Screws so that the Input
Flange remains evenly parallel to the Air Chamber.
Refer to Table 5 for the recommended assembly torque
values.
