Well, I put it back together after super-gluing that part back on as best I could (sorry Ron!) and after cleaning and re-oiling it its running better than before. Most noticeable is when stopped the armature spins twice as long as it did before. The speed is better, and while my present spring is a bodge consisting of thin solder wire wrapped tightly round the motor shaft, its running OK for now.

I guess epoxy would have been better, but if the motor fails I guess I will replace with one of Stamanns repro models, thanks for the advice folks. I will upload some pics of this so it can serve as a guide for someone else who wants to disassemble and clean their TT motor.

The parts catalogue lists 400912-A , Interestingly there is also a 50hz version listed (403102-A)! I guess this would be the 60hz model, with a spring already fitted :lol:


Either way the part number on my motor would suggest it came from an earlier model? As Rob says, potentially intended to work with a slightly different sized turntable


What I was thinking about is from a Rowe machine. I don't have either a R-O or Rowe T-T to measure, but the Rowe does appear to have a smaller inner diameter. typical Rowe part#'s for that motor are 300-05193 (M phono) and 300-0145 (L phono). What you find stamped on the motor might not even be a part# for the "house". One clue is the plug. On the Rowe motors the motor originally leads to spade lugs, one of which goes to a microswitch and untimately both end in a standard two prong house plug.

R-O 9IIRC) uses a nylon "Amp"-type plug. If the motor leads are spliced or otherwise not original, that would be a clue too.

Guy's,
It would be my GUESS that what ever type of plug you find on a motor, would have been added by Rowe/AMi. It would be my guess, that the motors were purchased with only leads on them, and the plug was added as needed. It would also be my guess, that any number found on motors, would be the motor makers part number, not Rowe/Ami's. Ron Rich
