Cracked crankshaft?

If that crank was MINE, I would take it to our big industrial machine shop in Macon and let them fix it. There are shops all over the country that can fix that crank so you'll never know it was there. This shop specializes in large industrial and railroad engines. The last time I was there, Gary, the owner I've known for over 40 years showed me an EMD crank that they had repaired. It was broken in TWO. They repaired it and the only reason you could tell where the break was is because it was clean in that area. He said a new crank was over $250,000 and they repaired it for about $1000. They do stuff like that all the time. Yeah, I know that locomotive diesel never sees 3000 RPM, but it takes probably 100 times the stress of an automotive V8 crank. I'd let a GOOD shop fix that in a hurry. But that's just how I am. my personal preference is to always try to make something good again.
