I can edit the list to take stuff off if we need to.
The Pacifics are ok, no actions required. I just haven’t had time to post up my findings,…..
for the record, and let this stand as notes for Dave on his master list, the problem locomotives are those with the forward facing Mabuchi 385 motor. As noted before, the locomotives with the large motors, ( usually Cannons, or Buehlers ) mounted in the cab areas, have a generous black large, nylon spacer that keeps the gear train centered…….

My original Post ",Wow, that looks like something I would wind up blowing up if I tried, lol. I have several of the K4 runs and haven't had them out of the box since no track big enough to run them on(unless I carpet run). I don't know if the TMCC 1361 K4 has that issue(wouldn't expect it to be, but what do I know). I guess we'll see more of these getting fixed when you are less busy with work and more engaged in "retirement", haha."
