After using plunger gauges on the loaded bearings, without the crank installed, I’m finding irregularities in the bearing inside diameters. With that information, how does a legit. machine shop attack this problem when the crank has been machined to a given dimension, particularly when working on older vehicles with limited parts distribution? I see where mechanics will interchange bearings and possibly mix bearing halves on a particular journal. I had a hell of a time sourcing over-sized bearings for this project to begin with. What do think a highly experienced builder might do?
