Runout tolerance given for guidance when regrinding crankshaft. When the runout on adjacent journals is in the
opposite direction, the sum must not exceed .003'* total indicator reading. When the runout on adjacent journals is in the
same direction, the difference must not exceed .003" total indicator reading. When high spots of the runout on adjacent
journals are at right angles to each other, the sum must not exceed .004" total indicator reading or .002" on each journal.
