B. Pivot Shaft Inspection
1. Verify that the Shaft (5), Snap Ring (10), and
Grooved Pin Rivet (11) are in place and secure. See
Fig. 1 on page 2 for proper location for Snap Ring.

hook, lower the Jaw (4) and apply operating pres-
sure to the air chamber.
2. With the Lock disengaged, as shown in Fig. 2 on

Plunger using replacement Jaw Kit C4200 of the
Rebuild Kit C4400.
