shaft sealing ring alternator and clutch side crankshaft (20x40/60x7mm)
for the following Vespa models
Note: Not suitable for mounting ball bearing 6204.
The mandrel does not have an undercut, so it would exert a load on the bearing inner ring. Furthermore it does not fit with Ø=48mm outside diameter into the bearing lane for the rear wheel bearing with Ø=47mm bore.
