Displacement Pump

Before starting:

To reduce down time, be sure you have all neces-
sary repair parts available. Recommended spare 
parts are listed in the parts list on page 15.

The balls (59) in the intake and piston valves cannot 
be reseated on the hardened seats (68).

Repair Kit 239320 is available. If you have a repair 
kit, use all the new parts for the best results. 

Whenever replacing packings, also replace the 
glands and bearing.

When cleaning parts, use a compatible solvent. 
Inspect parts for wear or damage and replace as 
necessary. Scoring or irregular surfaces on the 
priming tube (72) or polished inner wall of the riser 
tube (79) causes premature packing wear and leak-
ing. Check these parts by rubbing a finger on the 
surface and by holding the parts up to the light at a 
slight angle.

Use light, waterproof grease whenever grease is 
mentioned.

Disassembly

1.

Flush the pump if possible. Follow the Pressure 
Relief Procedure on page 6. Disconnect all air and 
fluid hoses.

2.

Clamp the motor base in a vise. Unscrew the prim-
ing cylinder (78).

3.

Hold the priming tube (72) with a 1/4 in (6 mm) 
diameter rod through the holes in the tube. Grip the 
flats of the priming position (71) with a wrench and 
unscrew the piston.

4.

Loosen the packing housing (70). Unscrew the riser 
tube (79) from the air motor.

5.

Remove the packing housing (70) from the riser 
tube (79), and remove the packings from the hous-
ing.

6.

Hold the intake valve housing (67) with a wrench, 
and unscrew the priming tube (72) by inserting a 1/4 

in (6 mm) diameter rod through the holes in the 
tube. Handle the tube carefully to avoid marring the 
surface. Remove the ball, seat, and gasket.

7.

Unscrew the intake valve housing (67) from the pis-
ton valve housing (64). Remove the ball and pack-
ings.

8.

Clean all parts thoroughly. Grease all parts except 
threads when reassembling.

Reassembly

1.

One at a time, place the female gland (74), five 
leather v-packings (66) with the lips of the packings 
facing 

up

, and the male gland (65) on the intake 

housing (67). Place the gasket (62), seat (68), and 
ball (59) on the housing (67).

2.

If the pins (80) were removed from the piston valve 
housing (64), replace them. Hold the piston valve 
housing with a wrench and screw in the intake valve 
housing.

3.

Place a gasket (62), seat (68), and ball (59) on the 
priming tube (72). Holding the piston valve housing 
(67) with a wrench, screw the priming tube into it. 
using a 1/4 in. diameter rod through the tube for 
leverage.

4.

Guide the riser tube (79) over the priming tube and 
screw it into the motor base, making sure the gasket 
(63) is in place. Torque to 50 to 70 ft-lb (68 to 95 
N.m).

5.

One at a time, place the female gland (76), five 
leather packings (73) with lips of packings facing 

up

a male gland (75), and a bearing (69) in the packing 
housing (70). Screw the housing firmly into the riser 
tube.

6.

Screw the priming piston (71) firmly onto the priming 
tube (72). Screw the intake cylinder (78) firmly onto 
the riser tube.

7.

Reconnect the ground wire if it was disconnected 
during repair.
