i would polish with 600 grit sand paper, then mike and see if the journal is round. they dont have to be perfect without flaws, but out of round .002 would be bad.

I polish cranks with 1000 grit grit sandpaper cut to almost the size of the journal. I wrap an old flat shoelace around the journal twice so equal pressure can be exerted around the entire journal then make sure the shoelace "walks" back and forth to get the entire journal. Wet the sandpaper with WD40. If the pits are too deep you probably won't get them out by polishing. Patience is the key here. You want to end up with a bright shiny finnish. Max. journal taper and out of round is usually .001. You may also want to clean up the sealing surface while you are there. Hope that helps. Gerard

I use Crocus Cloth the very same way..

It will Polish out a journal surprisingly well, using the wrapped method you describe..
