Alan,
Update on the 675. The replacement brush plate arrived this afternoon and I just installed it. Runs like a top! This had me baffled. I've never run into that issue and had tried everything I usually do to get it to run. The giveaway was the wobble I saw in the shaft when it was in (what was supposed to be) reverse and I could feel the magnets struggling to turn it. I put it under my high power illuminated magnifier (which BTW, is the best tool on my bench) and I saw the crack. And a bit of a bonus......I was going to rebuild the e-unit to see if that helped, but held off until I found the actual source. Good thing I didn't. This one works and proved to be one of the rare dead silent e-units. So, all is good and my friend will be pleased
Roger
