ＴＹ１６０和ＴＹ２２０型推土机的转向接盘与终传动Ⅰ级主动齿轮采用锥形花键连接，装配压力为７８～２００ ｋＮ。如果转向接盘的油封及与之相关联的零部件损坏，就得先拆下转向接盘，之后才能对其他部件做进一步检查。由于转向接盘与中央传动法兰盘之间的距离只有１４０ ｍ
The TY160 and TY220 bulldozers are connected by a conical spline to the steering gear of the final drive class I drive with an assembly pressure of 78 to 200 kN. If the steering wheel oil seal and its associated components are damaged, you have to remove the steering wheel plate first and then check the other components. Since the distance between the steering wheel and the central drive flange is only 140 m
