7/29/20: Yesterday, with the help of some knowledgeable Stovebolt experts, I was finally able to disassemble the engine and pull the crankshaft. What I found was not unexpected. The crank was already reground .030” under and the rear main bearing was ground to .027” under standard, which is .003” shy of what it should have been. We found the smoking gun.

Jerry suggested either find a shop that could handle regrinding the main journal the .003” it needs or find a another crank to regrind. If It could be reground, I would still need to address the rear main seal area.

I had a couple of Automotive Machine Shops in my area, recommended by some fellow “Bolters”, so I’m going to give them a call and see whether its possible.
