It depends which pump you have, on hayward super II you shut off the breaker, remove the rear motor cover, disconnect the electrical wires, then remove the 4 (9/16")bolts holding the motor to the "wet end" which is where the basket is. Now, pop off the diffuser, sometimes it stays in the wet end when you remove the motor. At the rear of the motor, use a 12mm wrench to hold the shaft, then unscrew the impeller (counter-clockwise) after removing the impeller, theres another plastic plate that lifts off, remove the plate, now there are 4 (9/16")bolts to remove in order to separate the motor from the seal plate. You have now broken down the pump. If you replace the motor, make sure to get a new seal as well (ps201)
