Bob,
The new complete pump was a mere $450 and for them to rebuild mine was even more with their labor rate. So I will be adding pump repair to my to do list. I see the parts break down for this pump, there must be a metal sleeve under the rubber impeller that I have to remove before I can get the shaft to pull through the body. Is there any trick to doing this? Maybe some gentle heat? This is not a complicated device, it is just one I am unfamiliar with. I may have to buy the impeller to see what it looks like before messing with this. The pump wasn't leaking or doing anything else interesting. Had I not disassembled it I wouldn't have known it was gunnybag.

I also see that guys have simply polished the shaft before rebuilding rather than replacing this $95 item. Basic rebuilding of this thing is not expensive at all, if you don't buy the expensive parts and you can figure out how to dismantle it.
