Ticking Speedometer '65 Convertible

Post by Scott J. Fonner » Sat Apr 14, 2018 6:38 am

Easy question. Speedometer is ticking, "assuming" it needs a new cable as ticking is in pace with speed and rolling barrel has a hesitation. How many hours will I have invested in replacement and how do I do it assuming it is the cable? Thanks in advance.

Cable change is easy but don’t go there yet. Describe the “hesitation” specifically, please.
Also, have you ruled out the odometer assembly?

Regarding hesitation. As speed increases, ticking sound begins and pace of ticking quickens, following speed. Speed indicator is not smooth or constant, it jumps in sync with ticking. Don't know where to start regarding odometer assembly.

Easy question... "assuming" it needs a new cable... How many hours?
To save on hours and headaches, I'd clean the cable (it's the least amount of teardown and build-up). IIRC, the manual has a basic cable replacement outline, but if I'm wrong it goes like this:
  • Remove the center clock pod, wiper/washer & vent knobs, etc.
  • Optional remove the radio speaker and other interfering equipment to make room
  • Cable end is now able to be reached coming in through opening.
On a MY65 the cable end has a nut; you can get it with a shorty line wrench. Bring the cable housing out through the clock pod and draw the cable out from the cable housing. Inspect it for any obvious problem--it ought to be perfect, no frays, bends, splits or anything. Clean it and reapply a new speedometer cable lube and put it back in if it's ok looking (if it is damaged, you can buy a new cable but, installation will be more work because of the new housing). When it goes all the way down to the transmission you have to twist it around until it seats into the gear--you'll feel that. Reconnect it to the speedometer pod.
Next, go for a drive. Still clicking, then you could still check out the drive gear in the transmission which is real easy, but that's probably not going to be it. Probably you're looking at a speedometer removal and surgery, which you can do yourself, but it will eat up a weekend. We'll be here. :smile:

The only thing I'd add to Paul's excellent advice is to spin the speedo with your hand while the cable is out, you might see or hear something. My speedo had jumped, and the drum was a bit bent, how that happened I don't know but I managed to fix it without any new parts. I'll also admit that I use light(er) duty chassis grease, not the real sticky stuff, on the inner cable. Never had an issue, knock on wood. good luck, Bob C

Just for info:
Mine would "tick" between 30 to 50. It was the outside drum part somehow had a tiny bend so it was barely misaligned as it rotated. Also I put a very tiny amount of clock oil on the gears when I repaired it and *knock on wood* it's been quite and smooth since.

That is what I'm hoping is the issue, but am now ready for worse. Thank you all.
