i got this Sony CFS-C7 from Japan. The cassette movement started working after changing the belt but the problem is the pitch roller which is not moving appropriately. Fast forward, rewind works without problem but when I push the play button pinch roller stops completely. Even without a cassette moves slowly. When I roll it manually I feel some resistance compare to other pich rollers( in different Boomboxes). I took the pinch roller out with pinch roller holder as I showed in the picture and cleaned it with alcohol but still the problem continues. Any recommendation? Is it possible to find this part? Thanks
Looking at the photos I have this feeling that rubber got separated from the plastic core. Push the center pin out to see what is actually happening. Agreed, it does not look too good: a little bulge in the center is good for tape self-alignment, but here it looks wrong
I haven't done any of this work for a long time but that bulge does look wrong, similar to this one on TapeHeads. http://www.tapeheads.net/showthread.php?p=426478 There's some information on pinch rollers on page 34/40 of this old MCM Catalog, they are now Newark Electronics, it might give you a part number to work with. https://web.archive.org/web/2005092...uct-details/text/mcm/html/cat49/section05.pdf I'd also check here, I think these guys are still in business, I called over the holiday but it went to voicemail. http://www.russellind.com/prbline/index.html And there's some parts on Ebay but you'll have to find an interchangeable part.
I either use a little pin remover and tap it out like this: or a watch pin remover tool like this: https://www.ebay.co.uk/itm/Metal-Li...870176&hash=item1c9d416795:g:D-8AAOSw~3paT0K0 either work fine.
