Runout tolerance given for guidance when regrinding crankshaft. Crankshaft for 4-53 supported on No. 1 and
No. 5 journals; runout measured at No. 2, 3, and 4 journals.
When the runout on adjacent journals is in the opposite direction, the sum must not exceed 0.003 inch total
indicator reading
When in the same direction, the difference must not exceed 0.003 inch total indicator reading. When high
spots of runout on adjacent journals are at right angles to each other, the sum must not exceed 0.004 inch total
indicator reading, or 0.002 inch on each journal.
