variator lock washer / pulley star washer for Piaggio, Vespa 50cc 36903 fitting for Piaggio Velofax 25 C02000 1999, 1,6 PS, 1,2 kw

Kickstart castle washer or fan wheel bracket is the counterpart of the kickstart pinion gear. This sits on the crankshaft in front of the variator and the teeth wear out over time, which leads to problems with the kick starter. Should be changed as soon as possible.
