Main Bearing Clearance

How do you get to that??? If it gauges out at .001 you have that all the way around!!!!:D

This I agree with, but it would equal a .002" difference in the OD of the crank journal and the ID of the bearing. So is that how it works? Or do you need a difference of .004" to get a clearance of .002"?
