Lambretta Crankshaft Woodruff Key and Vespa Clutch Key

Lambretta Crankshaft woodruff key 4 x 6.5 mm

This woodruff key is used to line up the flywheel when you fit the flywheel to the crank.  Contrary to popular belief it does not stop the flywheel spinning on the crank, only the grip of the taper on the flywheel does that.  If you find you are going through a lot of woodruff keys, you are possibly not doing your flywheel up tightly enough. 

Used on Lambretta LI, LIS, SX, TV, DL, GP and Serveta

Also used for crankshaft and clutch on
Vespa PX
Vespa Rally180 VSD1T
Vespa Rally200 VSE1T Sprint crankshaft / flywheel
