Internally the VCR contains many drive belts which are used in the
mechanics of tape transport. With age these belts become slack causing
malfunctions and when this happens the whole lot should be replaced. In
particular for the rewind function you will need to replace a tyre
on the supply reel.
Sluggish threading and capstan problems
The bottom bearing on the capstan motor is prone to wear and because this
motor also drives the threading mechanism threading can become sluggish.
When this happens you will hear a horrible squeaking noise!
It is possible to strip down the motor and replace the bearing but
an easier option is to replace the entire motor if you can find a replacement.
