DISPLACEMENT PUMP SERVICE

To reduce the risk of serious bodily injury, including

injection, splashing in the eyes, or injury from mov-

ing parts, always follow the 

Pressure Relief Proce-

dure Warning

 on page 8 when checking or servic-

ing any part of the spray/dispensing system, when

installing, cleaning or changing spray  tips/nozzles,

and whenever you stop

spraying/dispensing.

WARNING

(See Fig 3 unless otherwise noted.)

1.  Flush the pump with compatible solvent if possible.

Follow the 

 Pressure Relief Procedure Warning

 on

page 8.

2.  Disconnect the hoses, remove the pump from its

mounting, and clamp it in a vise. Unscrew the cou-

pling nut (9) and the tie rod locknuts (3). Remove the

cotter pin (1), loosen the jam nut (5), and unscrew the

connecting rod (11) from the displacement rod (108).

Pull the motor away from the displacement pump.

NOTE:

If you are using a repair kit to service the pump,

use all the new parts. See pages 15 and 17 for

available kits. Parts included in the kits are

marked with a double asterisk, for example,

(124**), in the text and drawings.

3. Place the pump housing (109) in a padded jaw vise

with the outlet (107) against one jaw.

4.  Remove the wet–cup (101), wet–cup packing nut

(136), and packing nut (140). Remove the packings

from the packing nut.

5.  Push the displacement rod (108) down so the prim-

ing piston (119) clears the intake cylinder (117).

6.  Use two wrenches to oppositely turn and loosen the

hex nuts (120) on the piston rod (122).

7.  Remove the valve plate (118), valve guide (121), and

the priming piston (119).

8.  Remove the intake cylinder (117) and o–ring (124).

9. Pull on the piston rod (122) to remove the displace-

ment rod (108) from the pump housing (109).

10. Remove the cotter pin (126) and unthread the piston

rod (122) from the piston valve (112).

11. Remove the packing nut (1 14) from the piston rod

(122). Remove the  packings and female gland from

the intake cylinder’s packing housing (REF 117).
