Did top end job on 06 660 and now ready to reinstall the cam. FSM says to temporarily put timing chain sprocket on cam but not put the bolts in, then put chain on sprocket. I find this not possible do do by myself. Is there another way to mount everything or am I missing something? I'm desperate to get this back together but working alone, while I do prefer this way it takes time. Can anyone help me a little? Thanks, Dave.
