Trip odometer

[86XL]

Mine doesn't work, the tenths spin but the numbers sit still. 

Options? 

Thank you.

Interested in this as well.  I've got to hit the trip reset about 10 times before all the numbers go to zero.

Sorry for the smart @as remark,

"No really"?

But with what sherlock? 

Years of jeeps?

Other options?

The tenths roller works, and you didn't say the speedometer doesn't work so I assume that's okay. From your screen name I assume we're talking about an '86 MJ, so you have a mechanical speedometer. The fact that the tenths (and, I guess, the speedometer) works means the cable isn't the problem. So the problem is in the odometer mechanism itself.

 

As far as I know, unless you work in a speedometer shop there are no how-to manuals for repairing an odometer. The Jeep factory service manuals certainly don't discuss it. You could pull the cluster out of the dashboard, remove the speedometer from the speedometer, and then remove the odometer from the speedometer and try to open it up to repair it. The closets I've come to doing that was swapping an odometer from one cluster to another to maintain the correct mileage on a vehicle that was getting a cluster replacement.

 

The Jeep parts manual doesn't list the odometer as a separate part -- they list the complete speedometer head with the odometer. So the simplest answer is to just replace the complete speedometer. The '86 uses the old style speedo cable, so your direct replacement would be from a 1984 thru 1986 (or maybe early 1987) Cherokee or Comanche.

Thank you.  That's what I wanted to hear.

You can also use a speedometer from a late 87 thru 90, but you would need a new speedometer cable because the end that attaches to the speedo head is different. (Although in a 30-year old vehicle, a new speedo cable isn't a bad idea.)

Isn't it true that if you have cruise, there is a very short cable from the speedo to the speed sensor, and then the main speed cable?  Point being, if you have cruise, you can just swap out that end cable to hook up the different speedometer.

That's likely correct but, as none of my Renix-era vehicles have cruise, I don't have any first-hand experience or knowledge.
