There are eight dowel pins on the end of the crank that mate with the flywheel. It is supposed to be a tight fit but it won't go on. I've cleaned everything numerous times even trying to polish the pins as stated in the instructions. But really, dowel pins are hardened steel and while polishing may reduce a .0001 burr, it's been fours of frustration that yielded no progress.
Tomorrow I'm going to hone out the eight holes with s strip of sandpaper, taped and rolled around a mandrel (an old drill). I'm guessing I'll have to remove .002-.004 on the diameter of each hole before it will slide on.
I can't find any other posts on thus subject. Has anyone else had this problem?
