My Pete rebuild

[Nostalgic]

I don't have micrometers big enough to measure the oil seal ends, unfortunately. I'm hoping that your theory is right, and it does sound plausible and fits with the way it was shipped. 2 chunks of styrofoam supporting the ends, crank in a bag, and tossed loosely into a box made of OSB. The measured "high" points on the ends were facing up.

Compared to the way the aftermarket crank I got a few years ago was shipped, it's kind of appalling lol.

All of that said, I'm sure that the last crank WOULD have caused me issues. It even made polished spots on main bearings 1, 4, & 7 due to the U shaped .010" bend. With everything new, I'm betting plastigauge shows .002-.003" clearances, which is my next step before it gets it's final bolt in and flipped over for pistons.

I've read that crank ends under high torque has a lot of bend and twist, up to .050" Again, an area I really don't know much about, which is why I've been relying on Quickserve to check everything.

I stumbled across this video, and ended up being fascinated by this guy repairing a broken crank, while wearing flip flops and working on a dirt floor.
