Abused pump - Now it's loud.

It's really not all that cost effective to have the bearings in a 1hp motor replaced. Most of the time you get a 90-day warranty ON THE BEARINGS only. A motor with loud bearings generally has been running hotter than designed and the windings begin to overheat. This causes deterioration of the laquer insulation and eventual failure. Most new motors come with a 1 or 2 year warranty. It's the same amount of work to remove and replace with a new one and you don't have to make a second trip to a motor or pool shop to pick up the motor when the bearing job is done.

For the Whisperflo remember to get a new shaft seal and all the O rings when you do a replacement or repair of the motor.

Poolman1, is it realistic for a DIYer to replace the bearings (thereby making it cost effective assuming the rest of the motor is still in good shape)?

What tools are needed? Any online instructions on what to do? Thanks.

Darrin, sounds like the pump cavitated (the water in it boiled), hence the effluent fitting's comming off. Whatever else got melted is uncertain (I've seen pump baskets that have melted down to ~ 2.5") it's probably best to replace the whole pump as there is a fair chance that the sealing areas warped.
Sorry I couldn't give you more optimistic advice -Waste

If you are certain that you want to have the bearings replaced, take it to a shop that does the work. To diy you would have to buy a bearing puller and bearing driver kit, bearings, shaft seal. You also would need an impeller wrench (if you are careful, experienced or both you can get away without this) so as to not damage the impeller when you remove it. The cost of these tools will outweigh the cost of having the bearings replaced.

You have to completely open the motor without damaging the wiring and without breaking the less than 1/8" through bolts that hold the thing together. Buy all the tools and parts and then break these and you'll need a new motor or shop anyway.

Just a few thoughts.

Thank you everone for your replies. I think I will just buy a new pump. I did notice a huge difference in my last electric bill - wow. The pump has turned into an electic hog.

Thanks again.
