Reconnecting the Displacement Pump

WARNING

To reduce the risk of pinching or injuring hands or
fingers caught between the hydraulic motor drip
pan and the coupling nut, always use connecting
rod adapter 184595 and tie rods 184596 on model
222900 Viscount Pump. Never use connecting rod
adapter 184451 and tie rods 184452 on Model
222900; those parts do not allow sufficient clear-
ance between the drip pan and coupling nut.

NOTE: On Premier models, ensure that the rod adapt-
er (102) has not loosened during maintenance. Proper
torque is necessary to prevent the rod adapter from
loosening during the pump operation.

If the rod adapter (102) has loosened during mainte-
nance, remove the adapter and apply Loctite

R

2760

t

(or equivalent) to the rod adapter and air motor piston
threads, and then torque as specified in Fig. 6.

1.

Use at least two people to hold the displacement
pump while another reconnects it to the motor (see
the CAUTION at left). Orient the pump’s fluid
outlet to the air or hydraulic inlet as was noted in
step 4 under Disconnecting the Displacement
Pump. Position the displacement pump (105) on
the tie rods (107). See Fig. 6.

2.

Screw the nuts (106) onto the tie rods (107) and
torque as noted in Fig. 6.

3.

Place the coupling nut (103) on the displacement
rod (1), then place the coupling collars (108) into
the nut. Screw the coupling nut onto the connect-
ing rod adapter (102) loosely. Hold the connecting
rod adapter flats with a wrench to keep it from
turning. Use an adjustable wrench to tighten
coupling nut. Torque as noted in Fig. 6.

4.

Torque the packing nut (3) to 128–156 N

S

m

(95–115 ft-lb).

5.

Reconnect all hoses. Reconnect the ground wire if
it was disconnected. Fill the wet-cup (3) 1/3 full of
Graco Throat Seal Liquid or compatible solvent.

6.

Turn on the air or hydraulic power supply. On
hydraulic pumps, open the hydraulic return line
valve first, then the supply line valve. Run the
pump slowly to ensure that it is operating properly.
