Okay guys hope one of you can help. I'm trying to fix the tape deck of my beloved Sony CFS-9000 at the mo. Its making a hell of a mechanical noise and isn't playing any tape. Now I've found out a gear is to much worn to manipulate the leverage system to ffw and rew any more.

Does anyone know which Sony apparatus uses the same tape deck? Or does anybody recognize the gear from an other tape deck. I'm also looking for the service manual to look up the part number. Maybe I can get a new gear from Sony?

 Gear has some worn tears. The black circle is a magnet thats sits on top of the gear.

The location where it sits.
