Teac A-3340 Capstan shaft 6mm and many others i saw some different numbersStandard shaft for most TEAC 1 4 inch machines not just the 3340, Before I was cleaning these up but there has been a huge discussion about the best way to do this, some people want to send it out to a shop to be done others like me put a bit of 3 400 grit wet and dry paper around an old pinch wheel and let it run.
