INSPECTION
The crankshaft journals should be checked for excessive wear, taper and scoring. Limits of taper on any crankshaft
journals should be held to 0.010 mm (0.0004 in.). Limits for journal roundness should be 0.008 mm (0.0003 in.).
Journal grinding should not exceed 0.254 mm (0.010 in.) under the standard journal diameter. DO NOT grind thrust
faces of Number 2 main bearing. DO NOT nick crank pin or bearing fillets. After grinding, remove rough edges from
crankshaft oil holes and clean out all passages. Crank journals must be polished smooth 0.10 micron ra.
CAUTION: With a forged steel crankshaft it is important that the final paper or cloth polish after any journal
regrind be in the same direction as normal rotation in the engine.
