9. Shaft Seal Change Instructions

When servicing electrical equipment, basic safety precautions should always be observed including the following.
Failure to follow instructions may result in injury.
WARNING


Disconnect all electrical power service to pump before beginning shaft seal replacement.

Only qualified personnel should attempt rotary seal replacement. Contact your local authorized Hayward Dealer or
service center if you have any questions.

Refer to Figure 9.6-1 for motor drive removal and mounting.

Refer to Figure 10.1-1 for pump component locations.
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.

9.1 Removing the Motor Assembly

1. Remove the six (6) 5/16" x 2" hex head bolts (item #20) which hold the motor assembly to the pump housing
(item #9), using a ½" wrench or socket.
2. Slide the motor assembly out of the pump housing (item #9), exposing diffuser (item #12). Remove the four (4)
diffuser screws (item #11) and pull the diffuser off of the seal plate (item #18) to expose the impeller (item #15).

9.2 Removing the Impeller

3. 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.
4. Rotate the impeller (item #15) counterclockwise and remove. The spring portion of the seal assembly (item #16)
is now exposed. Note carefully the position of the spring seal, and remove it. NOTE - Replace motor cover to
protect delicate motor parts.

9.3 Removing the Ceramic Seat

5. Remove the seal plate (item #18) from the motor by removing the four (4) 3/8" x 1" hex head bolts (item #21) that
secure it to the motor, using a 1/2" wrench or socket.
6. Press the ceramic seat with rubber cup out of the seal plate. If tight, use a small screwdriver to tap seal out.
