Nothing here is meant as a slight to Jeff or odometergears.com, he's a good guy and from all I hear produces an excellent product. But sometimes you just want to repair what's there and can.
I first did this on my first E21 when it didn't work with a mere 197K on it. I repaired the gear and last I saw of the car it was dead in a parking lot with 385K on it, suggesting at times this can be a long lasting repair although I lost track of the car when the kids sold it at ~350K. That was the early 90s and to the best of my knowledge there were no replacement gears available then. Anyway, this works if there is a simple crack or split, but not if there is a missing tooth as there sometimes is.
I make a reinforcing ring, I use 1/16 welding rod, a little smaller than the hub size, force it on, then glue it with a drop of superglue. Both sides. Then often it's not tight enough on the shaft so I have to score the shaft with a wire cutters. Pics show the crack and score mark. Plus a close up of my fingers.

Re: Trip ODO repairs
good tip Mike
my ODO isn't working, thus failed my licensing inspection.
So I had a go at puling it apart and see if I could repair it. My spare car ODO is not working also
pulling the ODO apart is reasonably easy
remove whole unit from dash
unscrew 6 rear screws
unscrew cable
the small gear that rotates the numbers meets up with the vertical work drive
unscrew 2 bolts holding back cover on
my gear has a crack
so pulled it off and added some super glue which will hopefully keep it together
I wonder if a small cable tie might work as well?
interestingly my other ODO has a black colour gear, which is also cracked!

Re: Trip ODO repairs
and if I want to buy a replacement gear, is it the e24 mechanical llisting on the web page?

Re: Trip ODO repairs
I don't mean to hi jack the thread about the odometer gears but I saw that you mentioned that your car would not pass the licensing inspection because of it. How strict is that inspection where you are? In Canada they check everything ie. You used to be able to rivet and seal a piece of metal over a rusted out part of a floor pan to keep exhaust gases out but now you have to have a certified welder do the fix!
PS.Nice fix on the odometer gears Mike

Re: Trip ODO repairs
who would have thought a working ODO was that important for 'petes sake"
