Solutions to Daily Maintenance Problems of Bulldozers

If the tension of the guide wheel spring acts on the track pin and pin sleeve, the outer circle of the pin and the inner circle of the pin sleeve are always subjected to high extrusion stress. When the pin and pin sleeve are in operation, the pin and pin sleeve are abraded prematurely. At the same time, the elastic force of the guide wheel tension spring also acts on the guide axle and sleeve, resulting in large surface contact stress, which makes the guide wheel sleeve easy to be ground into a half circle and the track pitch is easy to Long, and will reduce the efficiency of mechanical transmission, waste engine power to drive wheels and Crawlers.
