I am in the process of replacing the upper rails of my 560 (just got it, one is broken). I plan to replace everything including the chain. If woodruff keys have been installed I imagine that the camshaft will be offset from the cranksaft timing when I install the new chain and I will have to remove it to take care of it. Am I right?
Martin, I am a little afraid of trying your suggestion because I am not sure of what I am getting into. I'll see what I can do after a couple of beers. Thanks.
