10. Loosely install the packing nut (2).
11. One at a time, place a backup washer (15), a fe-
male gland (19*), one UHMWPE v-packing (17*),
two
v-packings (18*), one UHMWPE v-
packing (17*), a male gland (16*), and a backup
washer (15) on the piston stud (20).
Be sure the
lips of the v-packings face up on the piston. See
Fig. 1.
12. Add shims (14*) below the top backup washer
(15*), using as many as necessary to obtain a total
packing stack height of 0.950–0.975 in.
(24.13–24.77 mm).
13. Place the ball (13*) on the piston stud (20). Apply
liquid thread sealant to the piston threads and
screw the piston assembly into the displacement
rod (1), torquing to 200 in–lb (23 N.m).
14. Lubricate the displacement rod (1), and guide it
through the bottom of the pump cylinder (11) and
carefully through the throat packings.
15. Install the o-ring (22*) on the intake valve housing
(24). Place the ball (23*) on the seat of the intake
valve housing. Slip the o-ring retainer (30) onto the
intake housing and align the holes in the two parts.
Install the ball stop pin (21) through the o-ring re-
tainer and intake valve housing, and screw the
housing into the pump cylinder (11). Torque to
50–60 ft–lb (70–80 N.m).
16. Torque the packing nut (2) to 50–60 ft–lb (70–80
N.m). Fill the packing nut cavity with Throat Seal
Liquid (TSL).
17. Screw the displacement rod (1) into the air motor
connecting rod.
NOTE: If the ground wire was disconnected before
servicing, be sure to reconnect it before operating the
pump, and check to be sure the entire system is prop-
erly grounded.
