A case study of a crankshaft catastrophic failure of a motor vehicle and its failure analysis is presented. The crankshaft suffered a mechanical seizure on the crankpin no. 2 after 3 years in service. It was repaired and after 30,000 km the vehicle had a damage again, with a catastrophic failure on the same crankpin.

This paper presents an unusual situation for analysis of a damaged component of draw hook system and where has been lost the basic information about the causes of failure. Due to the lack of information, the analysis has a high degree of assumptions, being based on failure scenarios. The broken component is a link plate made of forged steel.
