Actually, while waiting for my bearings to arrive from Jeff, I amused myself by gluing a nylon thrust collar to the brush plate. Knowing that it wouldn't stick, I used the epoxy to surround and encompass the nylon washer, and it held! It totally quieted the bearing and made things run smooth as silk. Thought I'd give it a life test (short life test) before the real bearings arrive. Looky here
As it turns out, the "life testing" is an interesting experiment. So far the nylon washer is doing a super job - no increase in play at all. It has developed a noticeable squeak in the past few hours. I re-oiled everything, even the tread and flanges on the wheels! No change. I removed both connecting driver rods - still squeaking. Finally I remembered that this thing has pickup rollers - never heard them squeak before, but that's what it was. Got a lot of oil cleanup to do!
It also changed gears a couple of times, i.e. went into neutral - both times I was out of the room, so I will run it some more. I may ditch the CW-80 in favor a nice sine wave 1033 and run it all night to see if that changes anything. Hmmmm…… maybe it's that oil I put on the rollers!! 
Also quite surprisingly, no heat! I can easily touch the metal brush holders - not even warm! Of course there's almost no load since the engine is only pulling itself, but that kind of speaks to an efficient motor design - some motors seem to get hot just running with no load!
