1965 Chevy C10 - instrument cluster blues
I was riding down the highway and looked down at my dash. The speedometer needle is just floating back and forth, back and forth... and the odometer went to roll to 80000|9 and stopped.
Hmnn.
I haven't checked the cable or anything yet, as it was dark when I got home.
Any ideas on things to check folks?
Thanks.

You may have twisted the speedometer cable. Actually, that is an easy fix. Then the next problem is the odometer. I suspect that is what broke your cable. If you are good with your hands the speedometer can be removed from the dash and taken apart to see why it jammed at the turn of a big number. While in there put some light grease on the odometer gears to prevent this from happening again.

AntiqueMechanic, thank you for the suggestions. I've had the dash out twice since I've owned it, it is a bit of a pain, but doable. instrument cluster out of dash I will check that out. -W

You should be able to get the cable off the back of the speedometer without taking out the cluster. Some are a bit tricky.
How Sweet the roar of a Chevy four!

I took the cable off the back, and rode around the neighborhood, it was turning like a champ.
I took the cluster out, check out the speedometer and I found something to slide in there so I could turn it from the back... I could turn it so many times, then it would bind up a bit and I could feel and hear a click. Hmnn.
I took it apart further and eyeballed it, put a dab of grease on the moving bits, plastic gears... spun it some more, somewhere in there it stopped clicking and turned nicely, no more of that click.
I dunno if that solved it or not yet tho', but the odometer was turning past the |9.
I have the cluster back in, but of course I broke something else while taking it out... old trucks are fun.
Now I have to plug it all back up and get it sorted out.
Thanks for the tips folks.
If this doesn't work, I guess I'll have to buy one.

an update for ya folks. I got it all back in a few days back, but I had some other wiring things to fix while I was under there. I have all that wrapped up now. I took it for a spin yesterday and the speedo is working again. 07/29/2012 : instrument cluster taken apart, speedometer close up I think I might take the speedo cable completely out and lube it. Thanks for the tips folks. -W
