Abstract
An odometer assembly having a shaft on which a plurality of numbered counting wheels are mounted for rotation and including a rotatable service indicator wheel supported on the shaft next to the highest order counting wheel for rotation therewith until a flag portion which overlays the indicator wheel becomes visible to the vehicle operator. A drive mechanism between the service indicator wheel and the highest order counting wheel couples the wheels together for the aforementioned rotation and thereafter permits the highest order counting wheel to rotate with respect to the service indicator wheel. A rotatable reset lever means is also provided to counter-rotate the service indicator wheel back to its original non-indicating position.
