Hi all,

I have the 145 MPH cluster in my 86 Z28. I just installed a new crate motor and I was wondering if it's possible to reset the odometer to zero. This would be nice for keeping overall mileage on the motor.

The unit in the car is the 5 digit and tenths counter. Currently it reads 05xxx.x, so it most likely has already rolled over 1 or 2 times and is inaccurate. I'm not sure if the unit in my car is mechanical or electrically driven though.

I don't plan on selling the car, and even if I do the title reads 999,999 mileage (my state's way of saying mileage not accurate"), so I'm not worried there.

Any help and advice is appreciated. Thanks

 

I don't know of any way besides taking the plastic off and manually moving the numbers back

 

You can't roll back the mileage,it is illegal.

 

Not a good Idea to do it but yes it can be done.
I have changed speedos before from 120 to a 140. what I have done is take a pic of each of them seperate and together, for my records.
Just make sure you document it.
I can also have a St cop buddy of mine do some paperwork on them 4 me. He'll come over watch me do the work and then document it also.
Gov'ment likes a bunch of paperwork sooooo bury them with it if its ever a issue !!!!!

 

If its a 5 digit odo you are rolling it forward, not rolling it back. If the car is 10 years old or older there should be no reason not to do it.

 

I read something about how you need to put a sticker in the door with the original reading, new reading, date, etc for it to be legal. Might have been in a shop manual. That way it's documented, and you cant forget to transfer the documentation with the car if sold.

 

With the age of the car the mileage would be exempt on the title anyway, so "rolling it back" for restoration purposes shouldn't be a problem with title transfer issues
