Faults are often caused by overload or unbalance, and often starting from material weakness not detactable from outer surfaces or from mechanical scratches or damaged into outer surface. Any unormal activity before breaking? Resonance, vibrations, overload, damaged bearings, repairs or any operating moods deviating from normal. Operator knowledge and change? Age of components, earlier experience? Combination of causes is possible.
