Vic,
I used an installer tool at my uncles shop when I built the bottom end.
As far as the crank snout, it looks perfect, no scars, burrs, etc. from looking at the face of the balancer, it was hammered at least one maybe two times before.
I didn't see any excessive wear in the keyway, but that was just a visual check.
I haven't installed the new one just yet, although I did put it on a short ways ( just to rotate the crank) I wanted to get a new woodruff key since the old one was kind of "hammered" wanted to make sure and leave nothing to chance.
Definitely has a good interference fit with this one.well, if I don't get held over tonight, I should have most everything done to get it fired up.if not, tomorrow after work.
Have a good weekend!
Ben
