E. Install the new rotary seal assembly:
1. Insert the ceramic seal and the rubber gasket into the
recess.
NOTE: To help facilitate installation, apply a light
coating of oil to the outside diameter of the rubber
gasket. Make certain that the ceramic seal is kept
clean and free of dirt and/or oil.
2. Slip the remaining parts of the rotary seal assembly
onto the motor shaft.
NOTE: Apply a light coating of oil to the inside diameter of
the rubber drive ring.
F. Replace the impeller and diffuser removed in Step B.
G. Reassemble the pump body to the motor and mounting
bracket.
MOTOR REPLACEMENT
CAUTION: Before attempting to replace the motor,
make certain that the power supply is disconnected
and the systems pressure is relieved.
A. The motor can be removed without disturbing the seal
assembly or hydraulic components of the pump. Make
certain that the service factor of the replacement motor
corresponds with the motor being replaced.
B. Remove four bolts that hold the motor to the motor
mounting ring.
C. Break the motor shaft free from the pump shaft by using
an 11/16” wrench on the pump shaft and a 9/16” wrench
on the flats of the motor shaft. Unthread motor shaft
while holding the pump shaft.
D. Reassemble the new motor.
