Pump Reassembly/Seal Replacement

1. When installing the replacement seal into the seal plate, use soapy water to wet the rubber boot before
pressing it into the seal plate.
2. Remount the seal plate to the motor.

slide the seal onto the motor shaft. Ensure that the carbon face contacts the ceramic face of the stationary

through bolts for proper alignment. Do not tighten the through bolts until all 4 bolts are in place and finger
tightened.
