If the pins are close to being aligned but not properly aligned, it is such a big bolt, it will just force it down into place and will shear part of the pin and slot off, not a good thing. There have been several crankshafts and balancers ruined in this way.
I said twenty tries. Now that I know to offset it a little to let it rotate slightly while it is being drawn into place, I could probably do it in just a few tries now. Nothing like practice.
Have a great day,
