This study is on problem of jamming gears, which is one of the most degrading factors in hydraulic motor performance. The phenomenon of gear sticking to the inside of a hydraulic motor housing was mathematically modeled as quantitative value of wear, and then structural analysis according to the geometric shape of the motor was performed as an analysis. Also in order to improve the manufacturing quality, a method was proposed to lower the defect rate by statistically analyzing the manufacturing process for parts exposed to wear. The analysis showed that 62.6% of parts hydraulic motor were exposed to wear. For the future, optimization of dimensions, addition of clearance values, and improvement of manufacturing process should be further studies in order to minimize wear and increase the mechanical efficiency.
