850 odometer repair-reset to actual mileage?

I have the gear. I have found out my ECU mileage. I need to know how to set the odometer to correct mileage when I replace the gear. Has anyone done this that can offer me help. The link to how to get mileage from ECU on the early 850's is http:/

I have done this on a similar kind of odometer--the one for the

What you have to do is to locate the center shaft for the odometer wheels. When you find that shaft, you will see that you can withdraw the shaft if you remove the swage on the end of the shaft. I use the term "swage" because I think that is the correct term for deforming metal to make a catch or stop. Anyway you will find that the shaft has been made out of round by the swage. You will need to file off the swage with a miniature file whilst trying to keep all the filings out of the odometer and speedometer mechanism.

After you remove the out of round swage from the shaft, you can push the shaft out of the boss that holds it. You do not need to remove the shaft so far as to have the odometer wheels fall off the shaft. All you need to do is to move the shaft out of the boss and then you can make enough free play in the shaft to move the number wheels away from their drivers to adjust the three or four most significant digit wheels with a tooth pick. You probably would need to move the shaft more (and dislodge a digit wheel or two) to fix all digits, but it probably isn't worth the effort. Once you have set the wheels correctly, mate them up with the driving gears and push the shaft back through the boss. Fix the shaft so it doesn't move with a little dab of wifey's fingernail polish.

There are legalities >
