IMPORTANT SAFETY INSTRUCTIONS
PLEASE READ AND FOLLOW ALL INSTRUCTIONS
WARNING – Electrical Hazard - Failure to disconnect power may result in serious personal injury or
death. To avoid, turn OFF power to motor before servicing pump.
NOTICE- Only qualified personnel should attempt rotary seal replacement. Contact your local authorized
Hayward Dealer or service center if you have any questions.
Exercise extreme care in handling both the rotating and the stationary sections of the two-part replacement seal. Foreign
matter or improper handling will easily scratch the graphite and ceramic sealing surfaces.
Removing the Motor Assembly (See Parts Diagram on page 9 of this manual for pump component locations.)
1. Remove the four (4) 3/8" x 2" housing cap screws which hold the motor assembly to the
pump/strainer housing.
2. Slide the motor assembly out of the pump/strainer housing, exposing the diffuser. Pull the diffuser
off of the seal plate, exposing the impeller. (The diffuser may remain in the pump/strainer housing.
To remove, pull it straight out of the pump/strainer housing.)
Removing the Impeller (See Parts Diagram on page 9 of this manual for pump component locations.)
3. 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. NOTE - Replace motor cover to
protect delicate motor parts.
Removing the Ceramic Seat (See Parts Diagram on page 9 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 9 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
non-granulated 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 9 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.
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 9 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 four (4) 3/8”" x 2" housing cap screws. (Be sure
housing gasket is in place, and replace if damaged). Tighten alternately and evenly.
