Mark,
Sounds like a question for William Wayne. If the rust is just a light surface rust you might be able to save the crank by turning it .010 or .020 under if it has not already been turned under size. About 30 years ago a couple of Beech King Airs lost their wings in flight. The lower forward wing attach bolts broke in flight causing them to crash. The problem was traced to rusty wing bolts. The reason was Inter Granular Stress Corrosion. It seems that the rust traveled along the grain of the steel weakening it from the inside. I'm no Metallurgist, but if I were you I would seek council from the experts.
