Changing the bearings was actually a piece of cake. That's already done. My problems have stemmed from the long bolts seizing into the motor bell house--bi-metal binding/welding, whatever and they snapped off. I had run just the motor with the impeller with the old bearings and it ran true. But the disassembly caused the problems.
But I'm thinking if the motor fix doesn't work, it's really not worth replacing the motor (one estimate was higher than a new 2spd Superpump! And that's just for the parts!). I'm about $90 into parts, plus tools (but I get to keep those) and I don't need to pay someone else for the labor. If it works, I'm good for several more years. If not, new 2spd Superpumps can be had for $500 all in.
Can't test my new SWCG yet, though.
