I just repaired a board on a Beocord stereomaster and got everything working except that one of the rubber drive wheels is slippering so it wont get correct speed unless I press on its shaft. Further the motor is a bit noicy.

Where I can get rubber drivsheels or have them made? 

And is there something to do to reduce the motor noice? The recorder is in excellent interior condition so I dont think its any problem with bearings.
