(1949 3600) My speedometer quit on me yesterday, started by the needle not returning and responding "slowly" then eventually quit altogether.
I had a parts speedometer which seems to have the exact same issue; after cleaning out the nest of a VERY tiny spider (see my separate post on that in the General forum), I thought maybe I'd put it together wrong but now I don't think so.
- Clocksprings on both units are good.
- I've made sure there is no oil or grease of any form in the "clutch" on each. Dry and clean
- Everything turns freely, but the "clutch" isn't engaging on either.
I'm tempted to try some thin shimstock in there, if it's just wear? I've ordered a replacement but it's weeks out and yup, I can estimate the speed just fine off the tach but I'd love to have one working even as a temp fix.
