Reassembly

1.Lubricate the throat packings and install them in the outlet housing (5) one at a time as follows, with the lips of the v-packings facing down: the male gland (4*), one UHMWPE v-packing (3*), two PTFE v-packings (25*), one UHMWPE v-packing (3*), and the female gland (2*). Apply thread lubricant to the packing nut (14), and screw it loosely into the outlet housing. See Fig. 4.

2.Lubricate the piston packings and install them on the piston stud (27) one at a time in the following order, with the lips of the v-packing facing up: the shims (35; use 0–3 as required), the female gland (31*), one UHMWPE v-packing (30*), two PTFE v-packings (29*), one UHMWPE v-packing (30*), the male gland (28*), and the washer (26*). See Fig. 4.

3.Apply thread sealant and screw the piston stud

(27) onto the piston mounting stud (13). Torque to 50–70 ft-lb (68–95 NSm). Install the piston ball

(16*) on the piston seat. Slide the ball stop pin

(11*) into the desired set of holes, and secure with the cotter pin (12*).

4.Check that the coupling nut (7), jam nut (9) and adapter (10) are in place on the connecting rod (8). The bottom of the adapter (10) should be flush with the end of the rod (8); tighten the jam nut (9) down securely to lock these parts. Apply thread sealant to the male threads of the adapter (10). Screw the piston mounting stud (13) onto the connecting rod adapter (10), and torque to 50–70 ft-lb (68–95 NSm).

5.Place the flats of the displacement rod (1) in a vise. Apply thread lubricant to the bottom threads of the rod. Couple the connecting rod (8) to the displacement rod with the coupling nut (7). TIghten the nut securely.

6.Place the o-ring (6) into the outlet housing (5). Slide the displacement rod and connecting rod assembly up into the outlet housing (5) until the displacement rod protrudes from the packing nut (14).

NOTE: Before replacing the pump cylinder, note its orientation. Failure to install correctly may result in failure of pump or premature seal wear. Inspect the inner diameter of both ends of the cylinder for smoothness and size. The rougher and larger end should mate with the outlet housing (5) upon reassembly.

7.Apply thread lubricant to the top threads of the cylinder (15). Slide the cylinder straight up over the connecting rod (8) and displacement rod (1), being careful not to scratch the cylinder by tilting it. Screw the cylinder into the outlet housing (5).

8.Install the ball (18*), o-ring (19) and ball stop pin (17*) in the intake valve housing (21). Apply thread lubricant to the bottom threads of the cylinder (15). Place the intake valve assembly in the locking ring (20), and screw the ring onto the cylinder (15).

9.Reconnect the displacement pump to the motor as explained on page 14.
