Fixed my Speedo/odometer

I managed to fix my speedo today. It had been acting up for the last few thousand miles (odometer jumping ahead (10s and 100s) and then slipping, speedo bouncing, etc.). Finally, on Sunday, someplace in Kansas, the odometer stopped working completely, then the speedo started making load popping sounds and jumping (like the cable was being snapped). I disconnected the cable and drove home.

I took it apart today and replaced the broken plastic gear as well as the odometer wheels and "cams" from a spare speedo. I also "roughened" the shaft to keep the gear from slipping. Kind of a PITA, but I got is all back together and it seems to work well. We'll see how long it holds out.

Odo is on my list of things to do...do you need 3 hands, a big maginifing glass, and a cattle prod to fix it? I can break a bucket of nails, can't see good up close, and would need the prod just to get me goin'!

I've read the "how to" and it seems easy enough (up to the point where I get ticked off and sling out into the pasture)....I've put a lotta of things outta business with just one little drop of SuperGlue.

I didn't use glue, instead I used some pliers to roughen the shaft under the gear and forced it back into place. I was afraid the glue would get away from me and mess up the odometer wheels. I took all the odometer wheels off and replaced the parts from another speedo because they were somehow binding, than snapping ahead, causing the speedo and the cruise control to jump everytime the 10s turned over. The whole thing took about 2 hours, but 3 hands would help.

If you don't happen to have a spare speedo laying around those gears can be purchased from www.odometergears.com.

I also feared the uncontrollable superglue would cause the whole odometer to turn as one
I also chose to roughen the shaft where the first gear sits. I didn't use pliers, I used sidecutters to "notch" the shaft in 4 places. The gear was firm to reinstall on the shafy and I have done 3000km since the repair.
Looks like it is holding fine.

Actually, that's about what I ended up doing. The shaft is pretty hard so I used "cutting pliers" to make several small notches and forced the gear into place. Based on the force required, it should hold OK, I hope. I've only put about 100 miles on the repair, but I'm leaving for NJ on Friday.
