Unique is a strong word, and it applies to Rutt's Machine's crankshaft repair capabilities. That's because our grinding wheel dresser is the only one of its kind in North America. It's an AMC K-2000 that's capable of grinding crankshafts up to 89" in length with a maximum stroke of 15" and a rotating swing of 27". This amazing piece of machinery allows us to maintain a sharp wheel with perfect factory-like radiuses that are necessary to keep cranks from breaking. For crankshaft rebuilding and repair, we have the knowledge and the equipment to do the job for you.
