The suspension system of special tracked vehicle is using hydraulic piston pump to adjust track tension and control vehicle position change. During operation of vehicle on rough field, failure of suspension control was occurred due to the piston pump failure. In this study, investigation was performed to analyze the cause of hydraulic piston pump failure. Main reason of piston pump failure is strong peak pressure and insufficient structural safety of shoe. The static stress analysis considering peak pressure was performed to find the weak point of the shoe. From the result, it is confirmed that pass hole of lubrication is the weakest point. Improved piston shoe shows 27% decrease in maximum stress and satisfies the design target which is less than 40% of stress margin.
