The examples of crankshaft disintegration in modern internal combustion engines are considered. The cases of ICE crankshaft failure connected with the presence of manufacturing defects in them are analyzed: neck surface strengthening failure or its absence, metallurgic defects in material microstructure, necks and their lubrication grooves rough machining are analyzed. To determine the reasons of crankshaft disintegrations there was used a developed research complex for monitoring a structural state and analysis of motor car parts material disintegration during operation.
