This gear rides on a medium pod gear. The two gears together operate the odometer. If you only want to repair the odometer once then, it is recommended to replace both at the same time. The diameter of this gear is 8.65mm or .340"

The original pod was made in two parts, the disc and then the urethane gear. We manufacture the replacement pod as one piece. This ensures a stronger part with no failure possible. Recommended also to order 20 tooth gear listed above.
