4. Secure the shaft with a wrench on the flats of
the shaft and thread the impeller onto the shaft
(note left hand thread). Tighten the impeller until
it shoulders onto the shaft.
5. Place new quad rings onto the thrust plate.
Use a small amount of grease to hold the quad
rings from moving out of position. Place the
thrust plate over the shaft with the kidney slot up
away from the bearing. Kidney should be on the
pressure side of the motor.
6. Place the drive pin onto the shaft slot and hold
it in position with a screwdriver while sliding the
gerotor over the shaft and stopping at the thrust
plate. Line up the gerotor and thrust plate.
7. Install the cover onto the shaft; some sideways
movement of the gerotor is necessary. The
dowel pins should go through the thrust plate
and into the body. Do not force this assembly by
using a hammer or press, it will slide together
when it is in position.
8. Install the four motor cover screws and torque
to 23.0 N-m (17 ft-lb) in a cross pattern with the
first torque at 13.6 N-m (10 ft-lb).
9. Install the suction flange and screws.
10. Install the handle and screws.
11. Check for free rotation by rotating the impeller
by hand. If it does not rotate, remove the motor
cover, clean the motor parts, and reassemble.
Dust and dirt granules will impede motor rotation.
12. Install the cover plate using five screws and
lockwashers.
13. Insert the pump into the frame and slide it
forward until the keeper tab fits into the slots of
the pump (Figure

14. Pivot the pump clamp rearward onto the pump
(Figure 14).
15. Couple the discharge hose to the pump and
secure the latches
16).

(Figure 13).
16. Connect the hydraulic hoses to the machine.
Checking the Nozzle Sleeve
The nozzle sleeve
is slotted to allow water and debris to drain without
back flowing into the hose. Make sure the slot and
hole are free of debris.
