Probably any MB Speedometer
 

The odometer does not work as with many, and the ones in wreckers generally don't work. I know this is due to the last digit slipping on shaft. I know they can be re-cemented. It is the how that I am asking from anybody with the experience or knowhow.

Some red locktight (the low removal torque version) carefully applied to the junction of the zinc gear and shaft will fix the odometer.

I have also used epoxy, but that required removing the shaft and I got the numbers messed up (lost 20,000 miles or so).

You will need to remove the speedo from the cluster, probably, to do this. The zinc gear is on the opposite end from the brass drive gears. You only need to apply a very small amount of locktight to the gear/shaft interface and let it set -- you can test by sticking a small file handle or other similar object into the speedo drive and spinning the gears. Be careful not to "glue" the shaft into the housing!
