My odometer stopped working so I opened it up and found one of the teeth on the small gear was broken so I went ahead and bought both gears. I reassembled the speedometer/odometer and reinstalled it but it still doesn't work. Before starting this thread I read quite a few threads on the subject but wasn't able to find what I was looking for. I'm thinking the problem may be the motor that drives the gears, is there a way I check if the motor is bad? I did find the broken tooth so I don't think that the problem, is there anything else I should check?

Thanks

 

Same thing happened to mine. I used some compressed air to blow any possible chunks out of it and also helped it get started by hand while it was out. Once I did all that and plugged it back in I haven't had any issues.

 

Hmmm, interesting...How does one help it get started by hand while it's out?

 

I had the same issue after replacing both odometer gears. I thought I had recovered all of the broken gear tooth. Upon the second disassembly I found a very small piece of the old broken gear tooth stuck in the fixed gear preventing the new gear from turning.


You can rotate the rotor of the odometer gear drive motor with a piece of wire or small screwdriver. You can see the end of the rotor when you look at the end of the motor. After the second time assembling I made sure I manually rotated through a few miles.

Thanks for the replies. I took apart, blew it out and manually rotated the odometer and now it works, what a relief!

 

Besides a much needed thorough cleaning, the new large gear might also not have been fully seated against the main gears (away from motor) during the first reassembly...

Here is a pic of what I am talking about:


Make sure you push the gears towards the center of the odometer during reassembly. You should be able to feel when they are all the way in.


BTW: as shown on my photo, I was able to completely remove the motor without removing the needles and the face, but I don't recommend going that far! I think that it is safer to just follow the Youtube video and to simply slightly pry on the motor to gain just enough access to the gears.
