Reassembly

Refer to Fig 7 for reassembly.

1. Place an 8 mm (5/16 in.) dia. brass rod lengthwise in

a vise. Install a new piston seal (14*) on the piston

seat (15). Apply thread sealant to the threads of the

piston guide (12). Place the piston guide (12) secure-

ly on the brass rod. Using a 22 mm crow’

s–foot,

screw the piston seat (15) into the piston guide.

Torque to 21–27 N.m (15–20 ft–lb).

2. If it was necessary to remove the priming piston rod

(21) from the piston (13), apply thread sealant to the

female threads of the piston. Place the flats of the

piston (13) in a vise. Hold the flats of the rod with an 8

mm wrench, and screw the rod into the piston.

Torque to 34–41 N.m (25–30 ft–lb). Be careful not to

create burrs on the flats of the rod.

3. Use a vise with soft jaws to hold the displacement rod

(1) by its flats. Install the assembled piston guide/

seat on the piston (13). Apply thread sealant to the

female threads of the piston, and screw the piston

assembly onto the rod, using a 15 mm wrench on the

flats of the piston. Torque to 34–41 N.m (25–30 ft–lb).

There will be a small gap between the top of the pis-

ton (13) and the shoulder of the rod (1).

4. Place the outlet housing (9) in a vise. Apply thread

sealant to the threads of the bleeder valve (33), and

reinstall it in the outlet housing (9), making sure the

bleed hole faces toward the bottom of the outlet

housing.

NOTE:

The bleeder valve (33) has two sets of threads.

When reassembling, be sure to screw the valve

fully into the outlet housing (9).

NOTE:

It is not ordinarily necessary to remove the outlet

nipple (7) and o–ring (8*). However, if they were

replaced because of damage, lubricate the o–

ring (8*) and place it on the nipple (7). Screw the

nipple into the outlet housing (9). T

orque to

70–75 N.m (51–55 ft–lb).

5. Lubricate the o–rings (10*) and install them on the

cylinder (1 1). 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 170–185 N.m (125–135

ft–lb).

6. Lubricate the throat packings and glands, and install

them in the outlet housing (9) one at a time in the fol-

lowing order, 

with the lips of the v–packings fac-

ing down:

 male gland (6**), UHMWPE v–packing

(5**), 

 v–packing (3**), UHMWPE (5**), 

 (3**), UHMWPE (5**), and female  gland (4**).

Apply thread lubricant to the packing nut (2) and in-

stall the packing nut loosely in the outlet housing.

7. Carefully insert the displacement rod (1) into the bot-

tom of the cylinder (11). Push the rod up into the cyl-

inder and through the outlet housing (9), until it pro-

trudes 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 170–185 N.m (125–135 ft–lb).

9. If the rod guide (17) was removed from the intake

valve housing (16), reinstall it with the open end fac-

ing down toward the pump intake.

10. With the beveled side facing up, press the seal (41*)

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 sealant

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 cer-

tain they remain in position above the flats of the rod

(21). Torque to 27–34 N.m (20–25 ft–lb). Slide the as-

sembled intake check valve 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 bev-

eled 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 cyl-

inder (20) and screw the cylinder into the intake valve

housing (16), using a 24 in. adjustable wrench.

Torque to 170–185 N.m (125–135 ft–lb). Installation

of the intake cylinder (20) will seat the parts of the in-

take valve assembly (U) securely in the proper posi-

tion.

15. Slide the priming piston guide (24) onto the rod (21)

until it stops. Then install the priming piston (23), with

the flat side of the priming piston (23) facing up to-

ward the pump. Apply thread sealant 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 34–41 N.m (25–30 ft–lb).

16. Reconnect the displacement pump to the air motor

as explained on page 9.

17. Allow 2 hours for the thread sealant to cure before re-

turning the pump to service.
