Removing the Impeller
3. Hold the motor shaft from rotating by using a needle nose ‘vise grip’ or pliers to
hold the shaft at the opening between the motor face and impeller sleeve.
CAUTION: DO NOT GRIP IMPELLER SLEEVE.
4. Turn the impeller counter clockwise until it is completely free from the motor shaft
thread.
Removing the Volute (Casing) from the Motor
5. Unscrew the four screws securing the four legs of the volute to the motor. These
bolts extend through the entire length of the motor into the 4 legs of the volute.
6. When the four legs of the volute are completely disengaged from all screws,
carefully slide the volute off of the motor shaft.
Inspecting the Seal
7. Carefully
examine
the surfaces of the
carbon disk
(black rigid part of seal rotating
assembly, mounted on impeller) and the white
ceramic ring
(at seal stationary
assembly on the volute) for edge chipping, surface scratches, or uneven wear.
The surfaces should be smooth and free from damage.
