Default Re: Understanding Crankshaft journal hardness

Mike, I just finished picking up the aftermarket crankshaft from the machine shop in a neighboring city that had the Rockwell tester. The owner said he had 3 different readings beforehand on different journals and when I asked, he did one in front of me on the front journal that was at a tad over 50, but he said his three readings were all between 50-55. That appears to be a far cry from the 260-320 range doesn't it? Thoughts now? Any chance of salvaging this crank?
