On my 76 Vespa Grande the Woodruff key is gone/broken off. Does this piece break off easily or is it a separate piece not connected to shaft? (I have never actually seen this Woodruff key piece intact, only old black and white pictures). I know it fits in those little grooves on the shaft and makes the outer drum spin but I just dont know if its sperate or what.
Please dont tell me I need to buy a new crankshaft set up in order to fix this. OR is it possible to like get a new Woodruff key? If so is there specific keys for specific bikes/shafts? Where can I get a new/used key? Can I make my own key? (probably not a good idea for me considering I can barely make Jello). Or is this just one big dumb question?
