Oh, I should also mention that this particular engine apparently had a tendency to break crankshafts because they were hollowed-out a bit too much, so a crankshaft that hasn't broken in over a year is worth hanging on to if I can.
Nup, you can't put back what you've removed so leave it unless it's harmful. Mild scotchbrite or polish if you really must, if there's pitting from rust your expectations have to be realistic. Generally give it a good clean with toothbrush and brake cleaner/WD/CRC/Inox to get rid of oxide, you dont want to touch the metal itself.
Clean it, lube it up and get the digital calipers out and do some measuring.
Try and find someone with same crank and compare.
PS: If you are in and out of engines, then go and find the Hudy bearing extractor, pay the bucks and do it. Took me 8 years of knocking blocks on chopping boards with oven gloves. In an instant of buying and using the Hudy tool, the foolishness of old ways really hit home strong. Also, DO NOT install a ceramic bearing without a good bearing tool. Keeping it square on the way in and applying pressure uniformly is what it's about. You can feel the hair dryer and heat working too and the overall experience is a better feel of the tolerances in your engine block. Best investment for someone who's into the nitty gritty
