Reassembly

Service

1.Clean all parts thoroughly and inspect for wear or damage. Replace parts as necessary.

NOTE: Refer to Fig. 6 for steps 2 to 5.

2.Turn the base (47) upside down. If the bearing (70) was removed, press-fit the new bearing so its top edge is flush with the shoulder (S) of the packing cavity. After installation, measure the inner diame- ter of the bearing. It must be uniformly 35 mm (1.375 in.) to ensure that the piston shaft does not bind. If incorrect, size the bearing while in place; this can be done with a 35 mm (1.375 in.) diameter steel ball.

3.Grease the wiper seal (44*) and press-fit in the base (47).

4.Turn the base upright. Install the backup washer (45*) in the base (47). Grease the v-block packing

(46*) and install it in the base so the lips face up.

5.Place the o-ring (41) onto the air motor base (47). Place the gasket (35*) on the base so one of its notches (K) aligns with the optional fluid outlet (L).
