The Ford Barn - View Single Post - Is a lightened flywheel overrated? (I think so)

Mass does Matter, the rear main on a Model A has always be a strong point with Factory Babbitt, of the three bearings, except where the Babbitt has been replaced by incompetence.

The rear bearing is not the one that catches the most wear, it is the center Bearing, and the crank Bows from the heavy weight of the flywheel.

Just about every crank that has had a lot of miles will measure out about the same wear, on both ends, and the center will measure about 3 times more from the crank running bowed.

Get rid of the weight, and get rid of some of the wear.
