1999 Sony SLV-M91HF vcr problem

[rpm1200]

I once had one of the early Sony VHS VCRs which had a direct drive capstan motor. Once it got hot, the capstan would start binding up. You could see it stop, the video would freeze frame and the Hi-Fi audio would buzz. I think the flywheel/magnet for the motor was warping and getting hung up on something. I got it to work for a while by putting some washers on the flywheel side of the capstan but it continued to get worse.
