Removing the Motor Assembly
(See Parts Diagram on page 14 of this manual for pump component locations.)
1.
Remove the six (6) 5/16" x 2" hex head bolts
(item #20), which hold the motor assembly to the pump/strainer
housing (item #9), using a 1/2" wrench or socket.
2.
Slide the motor assembly out of the pump/strainer housing (item #9), exposing the diffuser (item #12). Remove the
four (4) diffuser screws (item #11), and pull the diffuser (item #12) off of the seal plate (item #18) to expose the
impeller (item #15).

To prevent motor shaft from turning,
insert a 5/16” allen wrench into the end of the motor shaft through the center
hole in the motor end cover/canopy.

out.
