Shaft Seal Change Instructions 

 

IMPORTANT SAFETY INSTRUCTIONS 

PLEASE READ AND FOLLOW ALL INSTRUCTIONS 

 

When servicing electrical equipment, basic safety precautions should always be observed including the following.  Failure to follow 
instructions may result in injury. 

A. 

  

WARNING 

– 

To reduce risk of injury, do not permit children to use this product. 

B.  Disconnect all electrical power service to pump before beginning shaft seal replacement. 
C.  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 11 of this manual for pump component locations.)

 

 

 

 

 

 

 

1.  Remove the four (4) 5/16" x 1 3/4" hex head bolts (item #6) which hold the motor assembly to the 

pump/strainer housing (item #4), using a ½” wrench or socket. 

2.  Slide the motor assembly out of the pump/strainer housing (item #4), exposing the diffuser(item #9).  Remove 

the two diffuser screws (item #7) and pull the diffuser off of the seal plate (item #13) to expose the impeller 
(item #10).   

  

Removing the Impeller  

(See Parts Diagram on page 11 of this manual for pump component locations.) 

 

3.  Remove the motor end cover/canopy by removing the two (2) screws and pulling off the cap/canopy away from 

the motor.   

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).   

5.  Rotate the impeller (item #10) counterclockwise and remove.  The spring portion of the seal assembly (item 

#12) 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 11 of this manual for pump component locations.) 

 

6.  Remove the seal plate (item #13) from the motor by removing the four (4) 3/8” x 1” (item #14) that secure it to 

the motor, using a 9/16” wrench or socket.  Remove the motor support base (item #15) from the seal plate (item 
#13) by removing the base screw (item #7) with a Phillips head screwdriver.   

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 motor shaft and seal recess in the seal plate (item #13) with a dilute solution of 

non-granulated liquid-type soap. 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 (item #13) with the polished side of the ceramic facing out. 

9.  Reassemble the motor to the seal plate (item #13) using the four (4) 3/8” bolts (item #14), and reattach the 

motor support base using the base screw (item #7) to the seal plate (item #13).
