I must be having a moment (again). I can't think for the life of me how it works. Yes you bend the tab up round the bolt head but what stops both of them spinning off together. Is it a case of as you tighten the bolt it creates an indent on the crank and this stops it from moving. The cam tab has a little nip in it that slots in withe the woodruff key but not the crank!
Please enlighten me.
Cheers
ps. its's a billet alloy pulley by the way
