68 ralley dash speedo

My speedo works but it doen't move the odometer. I haven't taken the cluster out yet. Anything simple it could be or should i just get another speedo?

Pull the cluster, get the whole thing restored. If you have problems with the speedo, other gauges may be having problems. Tim

Speedo it self works fine. All the other gauges work fine. Problem is odometer is not moveing.

There is a small gear that transfers movement from the cable to the odometer section... I've seen that gear pop loose from it's mount.. Take it apart & have a look..

Thanks. Thats a start. Maybe get lucky and easy fix.
