housing
7. Using a 5/16” socket or flat blade screw driver remove the 2
screws from the diffuser on the pump assembly.

the motor.
9. Using a 7/16" wrench, hold the motor shaft across its wrench
flats while unscrewing the impeller.
10. Remove the shaft seal from the impeller, make sure the
stainless steel sleeve comes off the impeller, all you should see
on the back of the impeller is the brass colored threaded insert.
11. Remove the ceramic seat and rubber boot part of the seal from
the cast iron seal plate.

the cardboard ring provided to keep the ceramic face clean.
You can use a little water or dish soap to lubricate the seal
pocket to make assembly easier.
16. Slide the square cut gasket over the flange on the seal plate,
make sure not to let the gasket twist.
17. Carefully slip the seal plate over the shaft so as not to disturb
seal position in the seal plate. The seal plate must be orientated
during assembly so the two holes are on a horizontal line
across the motor shaft.
18. Push the bellows side of the shaft seal over the impeller hub,
you can use a little water or dish soap to lubricate the impeller
hub to make assembly easier.
19. Holding the motor shaft with a 7/16" wrench hand tighten
threaded insert of the impeller onto the motorshaft. Lubricate
the nose of the impeller with Dow Corning III valve lubricant and
sealant or other potable water safe lubricant.
