6.2.4  Mechanical Seal Replacement

NOTE

  This is a two-part replacement process. 

The 

mechanical seal must be replaced as a set.

NOTE

  Refer to Figure 9 for the location of the mechanical 

seal and impeller.

 WARNING

Do not damage the ceramic or carbon surfaces of the 

seals. If surfaces are damaged, leaks will occur.

1. 

To access the mechanical seal, comply with the 

warning and follow steps 1 through 8 of 

Section 

6.2.2, Impeller Removal

.

2. 

Remove the carbon face seal half from the 

motor shaft, see Figure 8. This is a spring-loaded 

seal. Grasp the portion of the seal closest to 

the impeller body and pull the seal off using a 

twisting motion.

3. 

Remove the motor from the backplate by 

complying with the caution and following steps 1 

through 3 in

 Section 6.2.5

4. 

Place the backplate o-ring side down and force 

the ceramic seal out using a screwdriver or drift.

5. 

Turn the backplate o-ring side up and insert the 

new ceramic seal side into the backplate. Use 

great care to press the seal in squarely with your 

fingers. The ceramic is easily damaged and must 

be pressed in using only your fingers or soft 

tools. Do not use any lubricant other than water 

and soap solution.

If installing a new motor, remove the protective 

plastic cap from the motor shaft. Place the motor 

on the backplate so that the opening in the motor 

faces the bottom of the backplate. The starting 

capacitor on the motor should be at the  

12 o’clock position. 

5. 

Replace the four (4) bolts and washers holding 

the backplate to the motor.
