5.Lubricate the o-rings (10*) and install them on the cylinder (11). Apply thread lubricant to the top threads of the cylinder. Using a 24 in. adjustable wrench on the flats of the cylinder, screw it into the outlet housing (9). Torque to 159–221 N.m (117–163 ft-lb).

6.Lubricate the throat packings and glands, and install them in the outlet housing (9) one at a time in the following order, with the lips of the v-pack- ings facing down: male gland (6n), UHMWPE v-packing (5n), PTFE v-packing (3n), UHMWPE (5n), PTFE (3n), UHMWPE (5n), and female gland (4n). Apply thread lubricant to the packing nut (2) and install it loosely in the outlet housing.

7.Carefully insert the displacement rod (1) into the bottom of the cylinder (11). Push the rod up into the cylinder and through the outlet housing (9), until it protrudes from the packing nut (2). Be careful not to damage the piston seal (14*) while performing this step.

8.Apply thread lubricant to the bottom threads of the cylinder (11). Be sure the o-ring (10*) is in place on the cylinder. Guide the intake valve housing (16) up onto the priming piston rod (21). Screw the valve housing onto the cylinder, using a 24 in. adjustable wrench. Torque to 159–221 N.m (117–163 ft-lb).

9.If the rod guide (17) was removed from the intake valve housing (16), reinstall it with the open end facing down toward the pump intake.

10.With the beveled side facing up, press the seal (30*) into the recess of the intake packing nut (27) until it snaps into place. The nose of the seal should be flush with or slightly recessed into the face of the packing nut. With the threads facing down toward the pump intake, slide the nut up onto the priming piston rod (21) until it clears the flats of the rod.

11.Lubricate a new intake valve seal (26*) and slide it onto the rod, being careful not to damage the seal when passing over the flats of the rod. Slide the seal up until it reaches the packing nut (27). Apply thread lubricant to the female threads of the intake valve body (25), and slide it onto the rod until it reaches the nut (27).

12.Place a 7/8 in. wrench on the hex of the packing nut (27) and a 25 mm wrench on the flats of the valve body (25). Screw the nut into the body, making certain they remain in position above the flats of the rod (21). Torque to 35–41 N.m (26–30 ft-lb). Slide the assembled intake check valve (U) up the priming piston rod and into the rod guide

(17)as far as possible; this may be difficult due to high friction between the seal (26*) and rod (21).

13.Position the intake valve seat (18) so its large beveled side faces down toward the pump intake. Slide the seat (18) onto the priming piston rod (21) and into the intake valve housing (16) until it seats on the rod guide (17) . Lubricate a new seal (19*) and push it up into the beveled gap around the bottom outer edge of the seat (18). Be sure the seal is fully and uniformly positioned in the gap.

14.Apply thread lubricant to the threads of the intake cylinder (20) and screw the cylinder into the intake valve housing (16), using a 24 in. adjustable wrench. Torque to 159–221 N.m (117–163 ft-lb). Installation of the intake cylinder (20) will seat the parts of the intake valve assembly (U) securely in the proper position.

15.Slide the priming piston guide (24) onto the rod

(21)until it stops. Then install the priming piston (23), with the flat side facing up toward the pump. Apply thread lubricant to the female threads of the priming piston nut (22). Hold the rod (21) steady with an 8 mm wrench on the flats, and screw the priming piston nut (22) onto the rod with a 3/4 in. wrench. Torque to 35-41 N.m (26-30 ft-lb).

16.Reconnect the displacement pump to the air motor as explained on page 13.
