Speedometer Repair Mar 24, 2014 8:49:31 GMT -5

Does anyone have any experience disassembling the odometer? Some of you may remember last Spring I pulled my speedometer out because the odometer got stuck when turning over to the next 1000. Once I had it striped down, jiggling the numbers and blowing compressed air freed things up. I was afraid to try to disassemble it the rest of the way to ensure that everything else was still in good shape, so I put it all back together and reinstalled the dash (after I freshened up the dash again).

Everything worked fine until I put another 1000 miles on the odometer by the end of the season, and sure enough the odometer locked up again as it attempted to roll from 76,999.9 to 77,000.0 so I just reached under the dash and disconnected the cable, driving it that way the last few weeks of the season.

So I'm hoping someone has pulled the odometer completely apart, or maybe someone has an extra one or two that they'd be willing to experiment with and document the process. I'm sure there would be several people on here that would be very appreciative.

I removed the dash this morning, and got the odometer out of the speedometer head. A couple pictures below to show how it comes out.

Doesn't look like I can disassemble the counter dial... you can see a shoulder on the shaft at each end of the dial pack. Either they're pressed on, or the shaft is a two-piece shaft. I don't want to risk destroying it trying to get it apart. I'm first going to try to find a new one, looking both online, and calling some of these places that repair speedometers. If I'm successful locating a replacement, I may try to take the old pack apart, especially if I can get some pointers from one of these specialty shops.

Postcar came through with a replacement odometer... much appreciated as usual! I found that the original odometer's 10,000 and 1,000 counters were binding on the drum shaft, but by spinning them quite a bit playing with it, they freed up. I could probably have reused that drum, but taking the dash out isn't my favorite thing to do, so I reset the counter to the 77,000 mile reading, and put it in the speedo head, and put the dash back together.

I removed the 8 nuts that bolt the dash in when I pulled it, but only had 7 on hand when I went to install it. Then during the process of reinstalling the nuts, one of them slid between the brace and lower dash frame by the radio, and after a 1/2 hour trying to extract it, I said f*** it. I said worse than that during the 1/2 hour I tried to get that nut back, but you get the point.

So now I'm 2 short. And they're not 10-24 or 10-32 either, but it's close. So do any of you have a small handful of these nuts you can spare out of your stock?

Unless I can find them at some specialty hardware, below a 1/4" I've only seen #12-#4. The #10-24 is close, but won't quite work.

It turns out that the nut turns onto a #8-32 stud.
