Failure mechanism caused by irrationality selection on fitting clearance between hinge shaft and shaft sleeve of hydraulic excavator working equipment was briefly analyzed. A new calculated theory and method on fitting clearance between hinge shaft and shaft sleeve was put forward. And the calculated method was proved by analyzing a kind of excavator working equipment. The result showed that the method of determining the fitting clearance between hinge shaft and shaft sleeve is useful.
