In the use and maintenance of the track, it is important to ensure that the pin rotates frequently within the pin hole. When using new tracks, it is important to strictly carry out this task. Before driving every day, check if the track pin is blocked by soil and cannot rotate. If it is blocked, find a way to restore its rotation. Secondly, it is necessary to regularly inspect and correct the deformation of the track shoes to ensure that each pin hole is concentric and prevent eccentric wear of the pins. If a pin feels difficult to turn with a wrench, then the front and rear track shoes connected to this pin are likely deformed. A dedicated template ruler can also be used to measure whether the track shoes are deformed. The deformed ones should be corrected in a timely manner. The correction method is to support the sagging part of the deformed track plate without heating, and directly use a large hammer to hammer the guide part a few times to correct it.
