The cause of a diesel engine camshaft failure of BEML BL40 loader diesel engine confirming BS6D140-1.A fractured sample of camshaft was collected from the BCCL Sinidih workshop.For identification of material used in the camshaft,chemical composition and hardness value were determined using a spectrometer and Brinell hardness tester.Phase composition was confirmed with the help of an optical microscope.For mechanical properties and behavior of fracture of material used tensile testing was done conforming ASTM-E08 standard specimen and experimental value of ultimate tensile strength determined.The analytical analysis is done by analytical design.The stress analysis of the camshaft is carried out for the determination of the stress concentration level at the fracture area by FEM(finite element method)by using ANSYS work bench 14.Fractography analysis of fractured surface is done by SEM,the SEM photographs show an intergranular fracture,and also it indicates grain boundaries were embrittled.The results presented in paper intend to focus on the potential process of crack initiation to catastrophic that may help to think of improved design and manufacturing procedure for the same type of failure.
