The crankshaft journals should be checked for excessive wear, taper and scoring. See Fig 1. Limits of taper or out of round on any crankshaft journals should be held to 0.025 mm (0.001 in.). Journal grinding should not exceed 0.305 mm (0.012 in.) under the standard journal diameter. DO NOT grind thrust faces of No. 3 main bearing. DO NOT nick crank pin or bearing fillets. After grinding, remove rough edges from crankshaft oil holes and clean out all passages.

CAUTION: With the nodular cast iron crankshafts, it is important that the final paper or cloth polish be in the same direction as normal rotation in the engine.

The upper number three bearing (2) half is flanged to carry the crankshaft thrust load and is NOT interchangeable with any other bearing halves in the engine. See Fig 2. All bearing cap bolts removed during service procedures are to be cleaned and oiled before installation.
