10. Insert the piston guide into the retainer nut. Thread the

retainer nut into the pump manifold until it is hand tight.

11. Slide the piston guide tool (included in the repacking kit)

over the top of the piston rod and insert the piston rod

through the bottom of the pump manifold. Using a rubber

mallet, tap the bottom of the piston rod lightly until the

piston rod is in position in the pump manifold.

with the hole in the pump manifold during reassembly.

Improper alignment may cause damage to the transducer

gasket.

pump manifold and into the gear box housing. Tighten

securely.

16. Reassemble the inlet valve assembly into the pump

manifold.

17. For Upright Cart units, thread the siphon tube into the inlet

valve and tighten securely. Make sure to wrap the threads

on the down tube with PTFE tape before assembly.

Replace the return hose into the hose clip on the siphon

tube.

18. For Stand / Low Boy cart units, insert the elbow on the

suction set assembly into the bottom of the inlet valve

housing. Push the retaining ring up into the groove inside

the inlet valve housing to secure the suction set assembly

in position. Push the return hose onto the return hose

tting on the pump manifold and secure in position with

the return hose clamp.

19. Place the front cover on the gear box housing and secure

in position using the four front cover screws.
