1. To access the mechanical seal, see Section 6.2.2,
Impeller Removal and Replacement.
2. Remove the carbon face seal half from the motor
shaft (See Figure 15). 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, following
the steps in Section 6.2.4, Motor Replacement.
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
or soapy water.
6. Install the backplate by following the relevant
steps in Section 6.2.2.1, Impeller Reassembly.
7. Install the motor by following the steps in
Section 6.2.4, Motor Replacement.
