How to replace drive belts in a yamaha K500
It is a simple matter of getting the Service Manual, then obtaining the belt kit from Marrs Communications belt supplier and then determining how to get the belts into the mechanics of the deck,
If you are not a Tape Deck Technician, then this may seem like an insurmountable task as the transport need to come out or at least open access to it's rear to take of thrust plates and parts of the mechanism that is required to get the belts into the unit. As a Tape Technician of 40 some years, I can tell you that there may be other things in the deck that also need attention like tires on reel table or other idlers, other small belts not supplied in the kit and the oiling of the Flywheel and capstan bearing. If you JUST put belt in you are doing half a job and the deck still may not run at the correct speed. There is also technical equipment needed to set speed as well as test tapes. New belts almost always require that the speed is set to the reference standard of 3KHz or 3150Hz depending on what test tape you have. This kind of work can take over and hour and some machines depending on design can take two. Calibration is done to a deck by any of the good Technician I have worked with. This is currently my full time business so if you need my help, I am available.
I have a lot of belts in stock- I have been doing this for 40 years so far.
