Anybody know a way to adjust the speedometer on a CJ7 to zero? I have decided to put a long block in and thought it would be nice to set my speedometer to zero.

Thanks
 
FYI, in most states that is Illegal, and I don't think CJ would advocate us telling you how to do that on the open forum...

Ever watch Ferris Bueller's day off? :)

So, I can pay $100 for a new speedometer with zero miles and that is OK, but rolling mine to zero is wrong? :)

Actually, there is a place to say the mileage on the odometer is not the actual miles.
 
I guess I should have phrased my question differently... :)

How to you adjust a new speedometer to the correct mileage?

:chug:
 
It is only ILLEGAL IF you get CAUGHT:D
 
The key in Minnesota is - you can replace it, but then on the title you also indicate that.

There is no place to indicate - I turned the mileage back. . . .:D

With CarFax, it's pretty easy to get caught.
 
Mechanical speedometers have a turn isolator inside of them so that when the speedometer cable turns backwards (going in reverse) the miles don't go backwards. Like mylittlecj5 said, it's illegal to tamper with an odometer.

Replace is legal, manipulate the numbers on one (forwards or backwards) is illegal, period, end of discussion.
