I just got a new crank and bearings. The guy at the machine shop took the casting number on my old crank and ordered it from that. I got the new crank today and took it home. Well when I went to put it in, it wouldn't go. I quickly discovered the culprit is a flange on the rear of the crankshaft that is preventing it from seating in the back of the motor properly. Now the question. Should I wait till monday and have him order me the right one, or should I turn the flange off with a lathe? And if I turn it down, will that dmak it leak when i put it in? Im leaving for Hot August NIghts wednesday so it has to be done and tomorrow is my only day off until then. I appreciate any advice.
