Thorens TD-160 bent motor shaft

I told you $40 to $100.00. There not cheap. When I need a motor I buy the complete TT keep the motor and what ever else I might need at the time and sell off the rest. I end up getting the motor for free or for short money. I'm happy you found one. Keep us posted. :music:
 
I'm curious. How does this motor shaft get bent on these Thorens? I'd think it would take a stout blow to do so -- like dropping the TT and the first point of contact to hit is the shaft.

Usually shipping or moving, if the top platter slides off of the sub-platter and hits the shaft, especially if it happens more than once. I've had one I was able to get exactly true again. Another one, not so much.
 
Ya the platter hitting the motor. Thorens realized the problem further down the road and started installing the metal post on them to help the shaft not to get bent. A lot of it was just people not knowing how to remove the platter. :yes:

since you already have a bent shaft on your motor, and you're considering replacement, you could try some gentle rebending to see if you can get the wobble down. Can't say you'll correct it entirely but worth a try, can't lose anything as long as you are gentle on the pulley.

Remount the motor and note the eccentricity of the shaft/pulley. I'd use a small marker held close to one side and slowly push it in closer till it contact only that part of the pulley that is leaning over. That is the side you need to push to the opposite side. Gently and at mid pulley, push across, less is better than more. Re-run and see if the wobble decreases. If you think so, repeat till wobble is pretty much gone.

Also, read up on oiling the motor and try it to see if its running true and smoothly? If so, redo the spindle bearing by cleaning out and reoiling as well.

If it doesn't work, then prepare for the new / used good shaft motor and transfer pulley if needed.

Beware of marking the outer edge of the pulley with a marker pen. The nylon part of the pulley may not be directly coupled to the shaft. If memory serves, the nylon pulley is on a clutch arrangement which allows the motor to spin a full speed and the pulley catches up when the platter is at speed. The nylon pulley may move in relation to the bent motor shaft depending on handling!!! The motors are synchronous and if they are stalled the torque is dratically worse than when they are in synch with the mains frequency. The slipping clutch arrangement allowed for a quicker platter run up. I believe that this was one of the enhancements from a 150 to a 160. I have a TD150.

Hi,

... I use the Mose/Hercules II power supply with is one of the best mods I've done on my TD150 and TD166mkII

Hi Robert, could you please provide some more info on that power supply mod? I´m really interested.

Hi, how wobbling is bad? I found that mine is not perfect too? Should it be super study oh how can I check?
