Pump Cleaning
If foreign matter gets into the bunker pump, the flow
may decrease or stop. If this occurs, the pump will
have to be removed from the frame, disassembled,
cleaned, reassembled and installed back into the
frame.
1. Stop the Sand Pro machine, apply the parking
brake and remove the key from the ignition
switch.
2. Disconnect the pump hydraulic hoses from the
machine. Insert dust caps onto the exposed
hydraulic couplers.
3. Release the latches and uncouple the discharge
hose from the pump (
Figure 13 ).

5. Slide the pump to the rear of the frame and lift
the pump out with the handle.
Disassembly ( Figure 15 )
6. Remove the (5) cover plate mounting screws
and remove the cover.
7. Try to turn the impeller to free any debris from
the pump impeller and housing. If the debris
cannot be freed, proceed to the next step.
8. Remove the (3) screws securing the suction
flange and remove the suction flange.
9. Remove the (2) handle screws and remove the
handle.
10. Remove the (4) hydraulic motor screws and
remove the hydraulic motor cover, gerotor
element with drive pin, and the thrust plate.
11. While holding the impeller, unthread the impeller
from the shaft using a wrench on the flats at the
ball bearing. The thread is a left hand thread
that requires opposite rotation for removal.
12. Remove the shaft and bearing assembly by first
removing the retaining ring, then apply pressure
to slide the shaft and bearing out of the motor
side of the pump housing.
13. Remove the (2) lip seals by pushing the seals
out through the motor side of the pump body.
Inspect the pump components
•
Clean all foreign material off the parts. Do not use
abrasive cleaning methods on the hydraulic parts
or shaft.
•
Check the motor shaft for wear at the lip seal
surface. If it has grooves greater than 0.076 mm
(.003 inches) deep, the shaft should be replaced.
•
Check the hydraulic motor parts for wear. Any
appearance of displaced metal or surface
