Crank hub install
 

When putting the crank hub back on does it have to line up with anything? Its not keyed, but I was just wondering since I stuck it back on, do I need to pull it back off and reposition it?

Only if you want it to line up for judging TDC, like when adjusting valves and such.

ok well I'll just leave it then, I think its lined up w/ #6 TDC right now

Just a tip. While you have it at TDC, mark the balancer with a paint pen so you can easily find it again. TDC for #6 is also TDC for #1. Just compression vs exhaust strokes.

That's the same thing. The crank rotates twice for every time the cam does. 1 and 6 TDC are in the same position as far as the crank goes.
