Disconnecting the Displacement Pump

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 9.

1.Flush the pump, if possible. Stop the pump at the bottom of its stroke. Relieve the pressure.

2.Disconnect the air and fluid hoses. Remove the pump from its mounting. Note the relative position of the pump’s fluid outlet (R) to the air motor’s air inlet (S).

3.Unscrew the tie rod locknuts (112) from the tie rods (102). Remove the cotter pin (109). Unscrew the displacement rod (1) from the air motor (106). Carefully pull the displacement pump (101) away from the air motor (106). Inspect the o-ring (105). See Fig. 3.

4.Refer to page 15 for displacement pump service. To service the air motor, refer to the separate air motor manual (306982 or 307043), supplied.

Reconnecting the Displacement Pump

1.Lubricate the o-ring (105) and check that it is in place on the displacement rod (1). Orient the pump’s fluid outlet (R) to the air motor’s air inlet

(S) as was noted in step 2 under Disconnecting the Displacement Pump. Position the displace- ment pump (101) on the tie rods (102). Screw the locknuts (112) onto the tie rods (102) loosely. See Fig. 3.

2.Screw the displacement rod (1) into the shaft of the air motor (106) until the pin holes in the rod and shaft align. Install the cotter pin (109).

3.Mount the pump and reconnect all hoses. Recon- nect the ground wire if it was disconnected during repair. Tighten the packing nut/wet-cup (14) so it is just snug – no tighter. Fill the wet-cup with Graco Throat Seal Liquid or compatible solvent.

4.Tighten the tie rod locknuts (112) evenly, and torque as shown in Fig. 3.

5.Start the pump and run it at about 40 psi (280 kPa, 2.8 bar) air pressure, to check that it is operating properly.

6.Check for fluid leakage at the packing nut/wet-cup (14). Relieve the pressure before tightening the packing nut/wet-cup.
