Basically gotta remove your dash panel….unscrew the speedo from the dash panel tin….remove the pointer by lightly pulling up on it….remove the two screws that hold the faceplate….remove 2 more screws from the top mount cross bar….slide the odometer to the left and it should pop out…if the plastic piece that holds the tumblers is still there pop it off the tumblers and reset to zero by lining up all 5 tumblers….If not, make one out of rigid plastic bottle (I used an old plastic juice bottle and cut it out using an exacto knife)…
When putting it back togther, make sure that the 3 tumblers fit down over that piece of metal sticking up and the rolling gear on the right fits back together…hope this helps!

If you have the odometer wheel out just hold it in your left hand with fingers holding the first metal tab(left to right) and turn the gear with other hand until you have 9 in the ten thousand place. Then just keep holding the first metal tab and now hold the second metal and turn until you have 99***. Then you do the same for the rest until 99999. Then I just reinstall the wheel and then turn the speedo by hand a few turns until 00000. Hope that helps.

here’s a picture to help….The 2nd pic shows how the 3 tumblers fit back down over the metal piece…

Notes:

use a old wall mart gift card!! plastic bottles or milk jugs dry up and crack apart in the heat!!i live in Arizona, and extreme heat caused mine to break(tried milk jug) they also shrink & deform with heat…wallmart is good for something!!!  just cut the slots out with exacto knife.

Just a heads up…

For those who hate to mess with the stock gauge needles – you can remove the odometer by just loosening the two screws on the speedo face and sliding the tumbler out from under it…

It will come out that way – I have done it – just go slow and you will eventually be able to get it out and back in without taking off the needle.

Reinstall is the exact opposite – making sure that all the items listed above are adhered to.
