Nate , It appears that you are quoting the old crank myth , read the post below. Undersize bearings do NOT have thicker bearing material, they have the same amount of bearing material, but have thicker steel backing .therefore the strength of the bearing has not changed. Most automotive engines and the older tractor cranks are not heat treated or surface hardened, so grinding deeper is not a problem . Grinding is not the problem , why it had to be ground can be the problem . Heat treated cranks that have had a heat related failure are subject to a change in the hardness or strength due to excessive heat. Those with nitriding or tufftriding come with a completely different set of guide lines . Basically ,if the shaft is not nitrided and is not a heat treated shaft with a heat related failure , you can grind it to any size that you can buy bearings to fit. george
