Model A's had a lower breakage, because of the bigger shaft that was used, then the Model T's that had, or have about a 65%, or a little higher, crack rate. This is all caused by out of alignment, shaft and bearings.

There are two types of bearing adjustment.

No. 1 normal adjustment, .006, or less, which is doable, and safe.

No. 2 Try to save bearing mode. After you have .006 of shims used, you now would have an egg shaped hole, that if it were a oil pressure engine, most of the oil would be pushed out the sides of the bearing, to be thrown into the pistons, by the crankshaft, to create, an oil burner.

This is why K.R Wilson, recommended pouring every engine in this condition.

Also, your center line of the crank, and pilot shaft, and bearing would off, as in alignment

Herm.
