Thorens TD 160 knocking sound on motor pulley

[John Wilson]

I have an intermittant problem when playing at 33 on my Thorens TD 160 -- I get a continuous low but noticable knocking sound coming from the motor pulley. There is no problem playing at 45.

Has anyone else experienced this with a Thorens?

John,

There is a thread here who might help you.

Ask Joel. He's sort of Mr. Thorens himself. I'm sure he can help.

Bent pully shaft

If you lift the main turntable off and start the turntable, you'll see the motor, pully and belt driving the inner turntable. If the pully is wobbling, that's the culprit. You can try and straighten it, but you'll probably need a new motor.
