Okay, I was trying to pull the "E" clip from between the tenths and the mile position and something clicked. So I decided to see what that meant. I tried the odometer and now it it working correctly. I don't know what I did now how long it will work. But I think I will keep digging and fix it more broke.

rjent, thanks for the help on this one. I don't know what I did to free up the odometer but it worked. I could not stand it so I put the head all back together and tried it out with the drill motor. I ran it for 1.2 miles. So far so good. Only one problem, I forgot to put the ears back into position on the trip odometer and wound up with 111.4 miles. Go figure. Easy fix there. More pics

Here is the head all put back together and 00000 miles on it.

And here are the ears I mentioned earlier. Gotta get these dudes in place or you get crazy readings.

And here is the whole speedo put back together and ready to run again.

Sounds like you found the issue. Good for you. I have had mine rebuilt twice and it works fine unless I try to reset the trip mileage. Then I have to play with it for a while to get it to work agian. I just don't mess with it any more.LOL

I am with  you on the odo reset. DO NOT TOUCH!! I learned that on my original speedo. I think when I reset it was when it all went south for the stocker. It never worked correctly again. I had it rebuilt and paid all the good money for that. It stopped working after 6k miles so I decided to try and fix ti myself. It appears to be working correctly again.

I think I am going to order some parts and put them in there this week so it will be like new again. Two gears and a number drum should set me up for a long time again.

I really know nothing about speedometers but just tore into this one out of frustration. I figured I could not hurt it anymore than it was already.

Luke, does your speedometer move at all when you drive the car? Say if you are driving about 20MPH does the needle move up the scale an appropriate amount?

I have the opposite problem. My speedo stopped working about 2 weeks ago. It was making a slight clicking sound and that went away when the speedo stopped working.  My odometer still works though so I am pretty sure the cable is okay.  Anyone have any ideas?  Do I remove it and take it to a speedo shop or is there something easy that I can do?  BTW it's an 81'  Thanks, Tom

Sounds like the gear to the needle is short on teeth now that the clicking stopped.

Call John Dvorski at Red Line Gauge and Clock Repair in Humbolt, TN.  731-571-0766 or email him at redlinec@bellsouth.net.  Unfortunately he is in the other end of Tennessee from you but if you could coordinate with him and take it to him, he will fix it while you wait.  He is that good and his prices are way better than Roger.  John may tell you how to fix the problem over the phone.
