Crankshaft for the Honda DIO27 scooter: it converts piston motion into rotation and transmits it to the variator.
Replace it if the connecting rod has play, or if there is knocking, vibration, or loss of compression. When replacing the crankshaft, it is best to replace the bearings and oil seals as well.
After replacing it, check the assembly at idle and while riding: there should be no unusual noises, leaks, or play.
Parts are chosen by the model and the number in the name (Dio, Lead, Tact, and the version): dimensions can differ between versions, so check the part before installing it.
