I just purchased the 1 HP Round Flange 56J Up Rate Motor - PL1102 hoping it is the correct pump for my older Hayward SP-1600-D Super pump (1HP). That is the number that is on the clear basket lid. It was hard to find any other numbers. Will that motor work? My old A.O. Smith replacement pump showed a frame of U56J but I could not find any other pumps with a U. Just 56J. Also, if it is not correct, how do I return the motor.
Thanks,
Stan Miller
