Figure 1 shows the roller axle on the track-type bulldozer. The length L of the positioning groove directly affects the pressing force of the floating oil seal. This size was originally measured by the sample, and the quality is difficult to guarantee. For this reason, we have manufactured the inspection tool shown in Figure 2, which is equipped with the ring gauge shown in Figure 3. The diameter of the ring gauge D is equal to the basic dimension L of the positioning groove on the axle of the roller. The grade requirement is 1T5, and the gap and the contour block are opened. Before the test, place the indicator gauge of Figure 2 on the contour block in the ring gauge of Figure 3. The positioning screw is embedded in the notch on the ring gauge, and the positioning screw is closely attached to the inner wall of the ring gauge. The dial gauge is adjusted to zero. When measuring, it will be on the gauge
