Examination of failures of 750 mm Doxford marine engine in service, which occurred in side crankpins of Nos 3 and 4 cylinders, cracks being initiated in recessed fillets; it was concluded that recessed fillets should only be employed with substantial overlap of crankpin and journal, and that use of flexible coupling in center of large crankshaft is of doubtful value; it is noted that failure has arisen only when these crankshafts are subjected to exceptional circumstances.
