Woodruff Key Question
I installed an oem woodruff key in a new crank for a gp800. The crank paperwork shows the proper key placement such that the upper flat section of the key is parallel to the axis of the crank. Is this correct?
Also, the service manual calls for yamalube on the flywheel bolt. Seems at odds with board suggestions. Any comment?

if im not mistaken you should be using loctite on that bolt. yamalube would only cause you to overtighten, and possibly break the bolt- lubrication on bolt threads causes less tension/resistance- therefore causing you to tighten more than spec torque (even though your torque wrench reads correctly), in turn causing a possible broken or stretched bolt which will eventually break.
I may be wrong so you'll want others to comment before installing your flywheel bolt.

i didn't use loctite on mine or flyboys ski. we just tightened it down to spec. don't use yamahalube. it will come lose over time with vibrations.

It will be implossible for the bolt to come out I think. The oil pump is right on the end of the bolt so I doubt it will move foward. I use a tiny bit of amsoil on the bolt.

Thanks for the input, y'all. Any comments on the key position shown?

With the key in the slot and the flywheel installed you are good to go. It is self centering.
