Default 65 Motorola AM Car Radio Mechanical Question

Hi guys,

I have an old AM Motorola car radio. On the tuning stem coming from the radio there is a slotted plastic piece which accepts the knob backer for the tuner. On this radio half of the plastic piece is broken so it won't hold the knob backer on. I've removed the whole shaft to try to remove the plastic piece to replace it but it doesn't come off. Is anyone familiar with this radio and ever experienced this before? I've taken a picture for illustration. As always any and all suggestions and help is appreciated.

Thanks,
Steve

Is the plastic piece fixed,or does it rotate?

I've seen 'dual shaft' pots like that used in older car radios alot,the volume/tuning on the 'center' knobs,and the tone/balance on the 'outer' knobs,like a concentric setup.
On all the pots I've seen like that though,the second shaft was metal(brass/bronze?) and not plastic.

Hi DJ,

It's exactly as you described. The tuner shaft (outside part) is plastic and it rotates. The volume is brass and much sturdier and it rotates also. This radio is from a 1965 Mustang and over the years that plastic piece became semi-brittle from being exposed to the elements. I'm just unable to remove that "plastic" piece to replace it once I can find a replacement. There is a little metal clip that I thought would free up that plastic piece once removed, but it doesn't seem to. Any ideas? It baffles me.

Thanks again,
Steve

Hmm..
It's been a while since I've taken a pot like that apart..
IIRC,there may be a clip on the shaft,on the back of the pot?
Or maybe it's got the folded tabs holding it together,like the usual suspects?

It seems like you should be able to find a suitable replacement for it,I'm just not sure where... I think I have a few similar pots in my junkbox,if you think they'd be any help in your repair efforts..I'll have to look..(remind me tomorrow )

Hey DJ,

Here's a picture of the clip that goes on the back of the shaft. Hope this helps.

Hi.

If you cannot fix it, I see quite a few mid-60's Motorolas advertised on EBAY.

You might get one cheap and make 1 good radio.

That might not be a bad idea,really. Then you'd also have spare parts in case something else went awry.

You might be able to pick up another radio of similar vintage and salvage that part. This is old car swap meet season, or an old auto wrecking yard should have a stack of radios someplace. There's various places that specialize in refurbishing old car radios: Google, or pick up an issue of Hemmings and check the ads.
