Roll new OD forward?

Digging deep into the restoration requires a new speedo cluster. Old one is OEM 1981 and is afu. Have new omix Ada cluster and itís all at zero. Want to dial it fwd to match current dead odometer. This is NOT a roll back deal. Not now or ever for sale. Itís roll new unit forward to replace the old. Our state watches OD readings And how explain a old vehicle suddenly has zero miles?

How do resto mod guys do it?


Look it's a 4.6!

They take them apart, on the instrument cluster you have to release the chrome bezel carefully with a large flat driver, remove bezel and glass and then unscrew the speedo head.

Twist the retaining spring clip on the back and push down, it holds the odometer. Once odometer is out you can adjust the reels and select the numbers.

Put it back together.

This is quite easy to do, I may have adjusted a few vehicles over the years to better describe their condition.

A call to the state regulatory agency will get you the how to info. You won't ask a question that hasn't been asked before.

Yep and the TSM has instructions and images as well. Be careful around the very fine tension coil spring.

When ever I hear the word 'Jeep' I reach for my wallet.

Call your department of transportation. They will have a registration process for the new odometer. My wife's Z3M had the speedometer replaced at 11K miles in California. When we purchased it, it came with a required state certificate that noted the change.


This would much easier and safer than disassembling the unit.

This is correct, then they issue a cert. noting it has been replaced.
Not a big deal, happens all the time.
