Magnetek is the motor. We need the pump model. If it's a square lid with two black knobs to loosen it, it's a Hayward SuperPump.
The leak, if it's dribbling from under the motor where it meets the plastic body, means the seal set has broken or worn out and needs to be replaced.
Tools needed:
1/4" nut driver or socket
7/16" open end wrench
9/16" socket
Helpful addition: 15" of extension for the socket/ratchet to be able to reach beyond the back of the motor
To Replace:
Steps:
1) Power Off!!!
2) Unscrew the two 1/4" bolts on the back of the motor to loosen the end cap. Don't remove the cap yet. Sometimes the screws are seized and snap off.
3) Remove the four 9/16" bolts that mount the motor to the pump body and pull it away so you can get to the impeller. The diffuser may come out with it. Any water in the pump will come out. If you have a flooded suction, close all valves! Let the water run into the ground.
4) Remove the motor's end cap. Another 1/4" bolt is securing the capacitor. Remove it and move the cap out of the way.
5) Insert the 7/16" open end into the motor, towards the center shaft. It has a couple of indents that when lined up (rotate the impeller to turn) will allow the wrench to slip over the shaft.
6) Unthread the impeller from the front of the shaft. The wrench will hold the shaft.
7) Replace the seal set that is now exposed, one seal with a spring on the impeller and the a white teflon ring with a rubber ring holding it on the seal plate.
8) Reassemble in reverse order.
Sometimes the impeller is seized onto the shaft. You can try to break it off but make sure you can get a replacement. Sometimes, its stuck and there isn't anything you can do about except replace the pump. This doesn't always require replumbing if the original pump body is still OK. Then it's just removing the four 9/16" bolts keeping the front and back halves and moving the new back half to the front half and moving the electrical connections. Save the new pump body for parts!
