I'm replacing my existing speedometer/odometer and want to turn the odometer to all zero's, does anybody know how to do this task. I have checked with the state on the legalities, it's legal as long as the car is older than 10 years.
Speedos of the 70s and earlier are easy to run back. It's relatively easy to dissassemble and remove the gears to reset the numbers. The drill method also works well if you don't want to risk breaking the speedometer needle since it probably will have to be removed to disassemble the gears. I have run them back in as little as 45 minutes including removing and reinstalling the unit in the dash. Uh, that was before it was a federal offense to do so.
