    Polaris PB-4 bearings failing, repair or replace

    My booster pump motor bearings are failing. Does anyone have experience replacing the bearings. The pump seals are leaking also so I am l looking at a new seals and bearings vs a new pump. Where can I get bearings? Not sure of the age of the pump, I'm leaning toward new since this one is looking rough and the inside of the pump has some corrosion, pitting. What brands are worth looking at?

    Replace the motor and seal set. Changing the bearings and seal set on these isn't worth the effort, IMHO.

    I agree with Scott, except that if the pump is very old I'd just look at replacing the entire pump.
