Remove the motor end cover by removing the two (2) screws or pry off the cap covering the motor shaft. Hex shaped caps must be twisted off. 4. To prevent motor shaft from turning, carefully slide a 7/16" open-end wrench between the capacitor and the centrifugal switch (the wrench fits over the two (2) flats on the motor shaft). Some motors may require a larger wrench be placed in slot at end of shaft to keep motor shaft from turning. 5. Rotate the impeller counterclockwise and remove. The spring portion of the seal assembly is now exposed. Note carefully the position of the spring seal, and remove it. Remove impeller ring as well. NOTE - Replace motor cover to protect delicate motor parts. Removing the Ceramic Seat (See Parts Diagram on page 11 of this manual for pump component locations.) 6. Remove the seal plate. Note the tabs on the sides of the plate and the mating grooves on the front of the motor mounting plate. 7. Press the ceramic seat with rubber cup out of the seal plate. If tight, use a small screwdriver to tap seal out. STOP - Clean all recesses & parts to be reassembled. Inspect gaskets & replace if necessary. Seal Installation (See Parts Diagram on page 11 of this manual for pump component locations.) 8. Clean and lightly lubricate the impeller hub and seal recess in the seal plate with a dilute solution of nongranulated liquid-type soap. 9. Gently wipe the black, polished surface of the spring seal assembly with a clean, soft, cotton cloth. Press the spring seal assembly onto the impeller hub - black polished surface facing away from the impeller. 10. Gently wipe the polished surface of the ceramic seal with a clean, soft, cotton cloth. Lubricate the rubber cup on the ceramic seat and press it firmly and evenly into the recess of the seal plate - polished side facing out. Replacing the Impeller and Diffuser (See Parts Diagram on page 11 of this manual for pump component locations.) 11. Place the seal plate onto the motor mounting plate, aligning the tabs on the seal plate with the grooves on the motor mounting plate. 12. Screw the impeller onto the motor shaft in a clockwise direction. Tighten snugly by holding motor shaft with wrench as noted in step #4. Place the impeller ring back onto the impeller, with flange facing towards the diffuser. 13. Place the diffuser over the impeller onto the seal plate fitting positioning lug between the two (2) guides. Replacing the Motor Assembly (See Parts Diagram on page 11 of this manual for pump component locations.) 14. Fasten motor end cover by using the two (2) hex shaped screws. Slide the motor assembly with the diffuser in place, into pump/strainer housing, being careful not to disturb the diffuser gasket. 15. Fasten assembly to pump/strainer housing using the six (6) 3/8"" x 2" housing cap screws. (Be sure housing gasket is in place, and replace if damaged). Tighten alternately and evenly.
