Complete crankshaft for Suzuki AD scooters: a shaft with a connecting rod on which the piston works and from which rotation goes to the variator.
Replace it if there is play in the connecting rod, worn bearings and journals, heavy vibration, or knocking from the crankcase. The repair is usually done together with the bearings and oil seals.
- Also inspect the neighboring parts of the assembly: they often wear out together.
