Response to Hi, I have Pentair clean & clear plus ultra-flow with 3 hp Magnetek Century centurion pump part number 7-177453-03 (picture attached). It becomes very noisy recently, I found a few bearing balls. Is this A.O. Smith 3 HP square flange 56Y single speed motor the right replacement? Do I need new impeller, diffuser etc to switch the motor? a seal kit? Thanks, Nick
