How do you reset Odometer?

OK - I got my new speedometer and have removed the needle easily and replaced the gears and reassembled the speedometer. Now how do I change the odometer reading from 173,000 miles to 121,000 miles? Anyone have a detailed method they can share with me with pictures?

I could not do the move shaft method - see below.

Note the small star wheels on the steel shaft across the top of the odometer. Using a small pair of diagonal cutters, grasp the steel shaft inside of the plastic body above the leftmost odometer digit and carefully push it to the right. It is a press-fit in the case and fairly tight so a bit of force is needed. Move the shaft only far enough for it to clear the left case side, so that the shaft and star wheels can be lifted clear of the odometer number wheels.

I am thinking of cutting off the top gear shaft on the replacement odometer (gears that move the miles indicators) and rotating the gears to indicate the correct mileage. Then cutting the plastic ear off (side of the case) where the gear shaft out of my original odometer is positioned. Then making a small cut in the plastic supporting ear (new used case) where the gear shaft is held in place with my Dremel and slipping the gear shaft though the small cut and gluing it shut.

Any advice is appreciated.

Thanks,

Glenn

Cutting anything is a terrible terrible idea, the pin holding the grey gears WILL push out, that's all you should be doing.

If you have a replacement odometer you can just swap the whole carrier between from the new one to the replacement.

OK - I continued to attempt to remove the odometer shaft with the small gears and finally got the hang of it. I have removed and reset the mileage gears for over a hour and finally got the correct mileage. This is not an easy thing to do. Speedometer shops charge anywhere from $175 to $250 for this work.

I just swapped the odometer from the old speedo onto the new one. Is that possible in a pre-97?

I'm learning quite a bit about these speedometers Yes, it is possible to just switch the odometers between speedometers. Once the meter is taken apart, there are only 4 plastic tabs that just have to be released to separate the odometer from the meter movement (motor). I could have saved myself a great deal of work by doing this first. NO need to adjust the odometer if you have your original odometer with your original miles, but have a broken needle shaft like I did. You can just switch the odometers from one speedometer to another.

See the two clips in the top half of the plastic housing in the above photo.

I have the speedometer back in the TB - now I have to see how accurate it is tomorrow.

If memory serves, I had to use the single miles wheel (or was it the 10th's wheel?) to roll mine forward. As I recall, it was time consuming but easily done.

Do the wheels catch on one-way tabs that make rolling backward more difficult? It's been 4 years and I don't remember.

I rolled mine forward ≈ 9k miles so it would more accurately reflect the true mileage of the vehicle. I drive my Birdy ≈ 4.5k miles/year & my odometer went unrepaired for a couple of years.

As a habit, I write the date and mileage on all parts receipts on installation. It can also help having proper mileage for state inspection (no looks of suspicion as if I'm trying to cheat).

You can roll the 10ths mileage wheel back either direction. But, for any significant miles it will take some time.

Well, I installed my speedometer and drove it today and it seem to work fine. I now have to get on the highway and measure it at a mile at 60 mph to actually see just how accurate it is. Not a totally easy repair job, but worth it rather then pay a speedometer shop $200 - $250 to do the job.
