The design of the entire pump is Hayward, the motor could be one of several designs and quite a few manufacturers.

I've seen a few spark over the years, and quite a few lock ups under after winter conditions. That's not uncommon and you pool owners probably know that better then anyone, regardless of the brand.

AO Smith was quite common for a Hayward pump. Who AO Smith has making their motors and where could be a factor too.

The point being it's an electrical motor like any other, when isolated from the rest of the parts of the pump. Treat it as such.

Bring it to an eletrical motor place that specializes in that stuff. You might save a few bucks rather then a new pump and they may even gaurentee their work for a certain amount of time.

I had a alternator rebuilding specialist who loved working on them and did it for a fair price. That was few years ago though .
