[Keith True]

Inserts are not forgiving at all.Once that few thousandths of babbitt is damaged it is steel-to steel on the crank.you said you have inserts,but then I see you mention shims.I didn't know you could use shims with inserts.Although,the Allis-Chalmers WD 45 uses inserts,and the center main has shims.Never quite understood that one.
