re: FX-90

I have just replaced the belt on my FX-90 to get it running perfectly again after 20 yrs of no use.

I used the AVBELT9 belt from cpc.farnell.com (81mm Diameter, 3.5mm Wide, 0.6mm Thick)

Cost was only 82p Sterling

Hi rickrhua,

I can't thank enough for that nugget of information - I've been searching for months for the specification of the belt.

How difficult was it to replace? Any gotchas in the process?

re: FX-90

Hi there,
Changing the belts on this deck is not too hard at all if you have done any work like this before.
It is fairly straightforward to remove the mechanism from the main chassis. There are just four screws that hold it in place. Once you have those undone, the whole cassette mech. just slides back out and then you can flip it on its back being careful not to snag any of the wires connecting it to the chassis.
There are now - I think - four more screws that hold the backing plate against the capstan flywheels. Undo these and you should have enough room to slide in your new belt. If the old belt has melted, you will probably need to remove the capstan wheels to get the goo properly cleaned.

I have also replaced all belts on my FX-A120 auto-sorting deck and that was a huge job which I would not wish on anyone.

Anyway good luck.
