There are potentially two gears that can go bad. First is the plastic gear on the side of the speedometer. Inspect closely where the shaft comes through the gear as there will generally be a hairline crack and the gear must fit tight.

Select a style:
1/8 = 3.175mm
3/16 = 4.7625mm

Second is the lead gear on the same rail. Check to make sure it is tight on the shaft. Using a small screwdriver, see if it spins on the shaft. If it does, you should replace this gear as well. There are three sizes. All you need to do is measure the overall thickness. Sizes are nominal
