Crankshaft gear for 2-stroke scooters with chain drive. The toothed wheel on the shaft transmits rotation to the drive of the engine mechanisms.
Replace the gear if the teeth are chipped, the splines are worn, or the engine is noisy. Gears work in pairs, so the condition of the mating part is checked at once. When replacing the gears, also check the keys and the seating areas on the shaft.
What to consider when choosing:
- number of teeth
- fit
- engine type
