I will always appreciate some suggestions.
Actually, when the washer was not riding into the screw, when I first assembled it, there was only a total of 1mm gap. The picture here is with the head of the screw actually recessed inside of the washer about 1mm giving the space between the two after the incident up to 2mm space now.
You missed what I said. The brass part isn't a washer per se...it's a bushing or spacer. There should be another much thinner washer between the brass bushing and screw. That would have prevented the screw from being sunk in like it did.
I think your crank shaft is fine, but I'd still suggest cleaning it off with a VERY fine grit sandpaper just to get the brass off of it and smooth any roughness. Get a new steel bushing like Gravedigger mentioned, and then you should be set.
