1st post after buying a well used(mudded) 800. I have flipped thru and read a ton of posts regarding this stupid design attaching the secondary clutch with double nuts to a threaded stud. But I must be real stupid or just not grasping what everyone describes.I have the helix, spring, shaft, and both halves removed but can not figure out how to get that stud off because it spins freely both directions and don't see a way to pin it in place. I want to remove it and replace it with an upgraded bolt since everyone says its a weak point if you keep original in. If there is a way to pin it do I just clamp some big vice grips on there and turn; is it normal or reverse threaded?
