一、主离合器轴与变速箱第一轴同心度的检查与调整1.同心度的破坏及其危害东方红—54/75拖拉机出厂时主离合器轴和变速箱第一轴的不同心度小于4毫米,但在使用过程中,往往由于车架前梁和发动机前支撑座的磨损及变速箱前支点螺丝垫片的松动磨损或错装使其同心度破坏。当主离合器轴与变速箱第一轴同心度破坏后,除增加机车转动阻力外,还会造成主离合器后轴承、变速箱第一
1. Inspection and adjustment of the concentricity of the main shaft of the main clutch and the gearbox 1. Concentricity damage and hazards The eccentricity of the main clutch shaft and the first shaft of the gearbox when the tractor is shipped from Dongfanghong-54/75 is less than 4 Millimeters, but during use, the concentricity of the frame front beam and the front engine support base is often damaged due to the wear of the screw spacers or the misalignment of the screw washers. When the concentricity of the main clutch shaft and the first shaft of the transmission is destroyed, in addition to increasing the rolling resistance of the transmission, it will also cause the main clutch rear bearing and the transmission to be the first
