This method of gauging run out is confusing. Suppose the snap ring diameter in the case exceeds the .006" limit due to it being out of round in a free state? This has nothing to do with the engine shaft. It seems to me this dimension should be verified before trying to determine if the case is concentrically located relative to the shaft. It appears there are 2 locating pins that locates the case. These were used to machine the snap diameter that is being indicated. Once you verify that the case is within spec then you can use the setup shown in the photo to check run out relative to the case.
