Generator (Gen) (1999-2004): Design: Freewheel
Certain generators are equipped with a freewheel between the rotor shaft and the pulley. The cover over the pulley nut in the center of the pulley indicates whether a freewheel is installed. Using the freewheel, the generator rotor shaft can only rotate freely in one direction. This means that any jerking in the belt transmission is minimized.
