Evidences suggest that the engine failure was progressive in nature. Examination revealed constant rubbing of the needle bearing cage with the rotor sleeve inner surface. Analysis shows that this was possible due to undersize of the bearing seating area on the eccentric shaft. The rubbing of the cage resulted in removal of the material from the rotor sleeve and thereby, making space for lateral movement of the shaft. The lateral movement of the shaft and the resultant induced vibration were responsible for the various damages seen on the engine components. A detailed analysis of the failure is presented in this report with a few recommendations for preventing recurrence of similar failures.
