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 (Figure 13).
11. Remove the ceramic seat and rubber boot part of the seal from the
cast iron seal plate (Figure 13).

14. Wipe down the seal plate to remove any debris or loose rust.
15. Push the ceramic seat of the shaft seal into the seal plate using 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 (Figure 14).
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 (Figure 15). Make sure after assembly the
back carbon and white ceramic surfaces are in contact.
19. Holding the motor shaft with a flat blade screw driver thread the
impeller onto the motor shaft, hand tighten. Lubricate the nose of the
impeller with potable water safe lubricant.
20. Replace the plastic cap over the motor shaft end.
21. Reassemble the diffuser, make sure the arrow indicating the top is
