My Polaris PB4 pump has always made more noise than the main pool pump. now it makes a high pitched sound. i took the pump apart and greased the shaft but this was unsuccessful. after reinstalling i noticed the pump only makes the high pitched noise when the cleaner is connected to the port in the pool. i think it may be the bearings in the motor but i canot find a diagram of the motor. your help will be appreciated

The motor manufacturers do not offer cut-away or parts diagrams. Parts such as bearings are purchased thru power transmission outlets locally. Parts for the pump should be found at a local pool store that sells the equipment. You will likely need a new set of 203 bearings, a flange gasket and mechanical seal. All told, the parts should be less than $40.

Dear John224,
My polaris motor is doing the exact same thing. With the parts you mentioned above, is this fairly easy to replace? I like the idea of $40 and a some elbow grease more than the $500 we were quoted to replace.
Thanks,
Not to bad but even if you take it to a shop it should still be under $100. The biggest thing is getting the new bearings on without damaging them which is best done with a bearing driver...something most people do not have in their tool box.
