I have a pentair Dynamo 1 hp pump, and the motor is sqalling. Mainly after it's been off for a while and I re-start it and it go's away after it runs awhile. I was wondering if anyone knew if the bearings could be replaced in the motor. I checked to see how much a new motor costs and I might as well by a whole new pump. But if the bearings are replaceable it would save me a bundle! Thanks.
