    AO Smith/ Century Pool/ Polaris Pump beraing help

    I had to rebuild my Polaris cleaner last week, waited 10 days with the pump shut off for the parts to and the time to rebuild the vac. That done, I put it in the pool and turned it on, horrible screach out of the pump. Need to replace the bearings

    I have searched google, pool parts distributors and now this website. I have gotten several different bearings, some measured in MM, some in inches, some say same size front and rear, some say bigger on the spindle.

    The info from the pump
    CENTURY POOL & SPA 1081
    A O SMITH
    CAT 625 FRAME N56CZ
    3/4 HP SF 1.5
    HZ 60 RPM 3450
    VOLTS 2230/115

    Any info on the correct bearings with a source / part number would be greatly appreciated

    Thanks

    Gary

    Welcome to the forum!

    Have you taken the old pump apart yet? Most bearings have the number stamped on the seal and you can just match them up.
