Does anyone have experience finding a good replacement radio dial belt fo the AM/FM Delco model 9283295? I have a 63 Sedan DeVille. My belt is slipping and I’m thinking that replacing it with a belt less prone to slippage I’ve time is my best approach. I have attached a couple pics for reference.
Thought about my issue a bit more, and instead of blaming the belt For being worn out and slipping , I thought about the resistance / friction of the dial mechanism itself. I proceeded to pulling the skins off the radio, and spraying electrical contact cleaner on all the rotation points in dial drive train that I could see. I have read and found it to be true that contact cleaner can not only remove dirt, but can also dissolve caked up grease/ oil. I then proceeded to use synthetic grandfather clock oil to precisely lube the dial drive train at all the same rotation points. Problem solved.. at least for now... Time will tell if this fix holds.
This approach made sense because many of the issues I see with this particular car have to do with what sitting in a garage for 15 years will do. Old grease and lube are particularly vulnerable. Incidentally, this same approach of using contact cleaner and clock oil got my clock to “run like a clock”
See picture attached.
You did exactly what I do and would have suggested ... open up the radio case and lubricate with electrical contact cleaner. I do this for all radios I pull in from parts cars, especially where the belt is slipping. Just to add, I have a test area set up with 12 volt source, antenna and and original speaker with connector. The tuning knobs often get debris and gunk in them and I will spray directly into the tuning shaft turning back and forth to clear up the static noise. I did this just yesterday with the am only radio I just posted. I will also lightly spray with compressed air to flush out any remaining debris.
As far as the belt slipping it can and often is a combination of loose stretched belt and resistance from internal moving parts. Cleaning the internal moving parts is done has you have noted. I have found the best replacement belt is a 190J6 micro-v belt that Mark Anderson had posted at This Link a few years back. The only diffence is I like to use 2 V sections of the belt as it gives a better fit in the tuning wheel grooves.
