were inappropriate material microstructure, notch effect and cyclic loading. The repair of the excavator based on the implementation of the axle made with use of material with suitable microstructure without Widmanstätten pattern. What is more, design of the axle was changed. Groove sensitive to fatigue crack notches has been removed. Instead, the new joint with hole in the axle was designed. Such solution is less sensitive to notch effect. References Brooks, C.
