Hayward pump cutting out several times a day - is this normal?

[Tommy]

Aaaahhh the good news keeps coming ...

Just one more thought in my own defense:

When I removed the pump motor and got the impeller to turn freely, I energized it on a cinder block while it was still isolated. My ears did not hear bad bearings! And I know what bad bearings sound like.

Just sayin' ...

Meanwhile, I have since learned (thanks to wonderful YouTube) that the front & rear bearings are '6203', available via Amazon, etc. for a fraction of the cost of a new motor. All you need is a 3-arm bearing puller, a strap wrench (to grip the impeller), and some patience.

I'm baaaaaaaaaaack!

I started this thread last year and described several symptoms. I can now say this: if in doubt as to whether you have bad motor bearings on a Hayward pump, wait a year. It's now quite obvious: my bearings are toast. I had to really work to (manually) get the impeller to rotate and the bearings sound awful! And the motor is running hot and all the rest.

So, given my motor: A.O. Smith UST1102 (Model No. C48K2N117A9; 1hp; 3450rpm), can anyone say FOR SURE what bearings to order?

I have heard "6203" (both ends), but when I went up on Amazon (for example), I see various 6203 flavors:

6203ZZ, 6203-2RS, 6203-2NSE, 6203RS, 62032NSENR, S6203-2RS, 6203, etc.

I suspect these may all be the same thing (size). Is the main thing the dimension spec: I.D. x O.D. x W (17mm X 40mm X 12mm) ??
