    reinstalling pump motor on hayward north star

    The pump on our pool is a a hayward north star and has stopped working. We have the same exact pump running our hottub jets and we want to put the motor from the jets on the pool. We have both motors off and are trying to get the motor back in and are having a hard time. Any tips to push the motor completely in so we can hook up the motor.

    any tips would be great

    Replace the SPX4000T Seal Plate O-Ring, SPX4000Z1 Diffuser O-Ring, and the SPX3200SA Seal Assembly. Make sure that the diffuser O-ring and seal plate O-ring are seated properly. Make sure that the diffuser is properly seated. Lubricate the O-rings with a silicone lubricant, such as Dow Corning 111 valve lubricant.

    Here is the manual that has a step-by-step instruction of how to change the seal.

    Here is a video showing the NorthStar being disassembled and rebuilt.
