CASSETTE BELTS (Page 1/2)

How do you tell what size belt for radio with cassete? Anyone in the Fiero community do these repairs?

Unless you can find a manual for the unit good luck. You can get belts from Newark /MCM Electronics. If you still have the old belt you could measure it but I know sometimes they turn to goo. Might possible contact Replacement Radios.com as they repair a lot of car radios.
Hope that helped.

Some years ago I was in a pinch for a cassette belt and picked up a bag of assorted rubber bands at a flee market. You know the rest of the story. Mileage may vary....

Your best bet is to just purchase an assortment of belts and see which fits the best.

Pretty sure that the assortment packs are not going to have the right one..
You can use a string or a wire to carefully measure out the circumference that you need. Also be careful to measure the size of the square cross section.
There are only a few sites out there that sell belts.. they have to be fairly fresh. A 10 year old belt is worthless.
And then the fun.. buy it and try it. If it is too loose, shave off some milimeters and try again.
I recall doing this for mine, and it was a compromise that never really fit right.
If you come up with dimensions that work, let us all know.

Now you have me wanting to rip mine apart since it's sitting on a shelf in my garage just to get a measurement for everyone.

Edit to add......I just found Ronald Finger's video on Youtube where he repairs his factory cassette deck and actually says he bought a bulk pack from Amazon and he found a few that worked. They give multiple thickness belts so he just needed to use the proper thickness. Here's a pic from the video where he taped his together with blue tape to find the right size.

Alright, I took mine apart and my belt was barely holding on. It was perfectly form-fitted to the pulleys but I was able to take it off with almost no effort. I cut it and it measures 8.5 inches so I'm guessing an 8" belt would work. I just ordered an 8" and an 8.4" belt. We'll see what happens when I receive them.

This is what mine looked like:

In case you didn't know, in the very early 1990s, Pontiac sold their cars with CD players by Delco that have all the same colours etc. and look like a dead ringer for the cassette decks.......stuck one in my 88 and never regretted it! Goodbye to belts forever!

I've fixed almost a dozen home audio cassette decks made in the 80's and 90's, the belts in those vary quite a bit, typically square, rectangular, and flat belts, of varying thicknesses.

Well the company shipped my belts today. They are coming from Oregon so hopefully I receive them near the end of the week. I'll post a pic of the fit.
