注意

在检验、保养、测试、调整及维修发动机时,请小心确保盛接流出的液体。 在打开或拆解任何储有液体的部件之前,要准备好合适的容器收集液体。

有关适合收集和盛接卡特彼勒产品上的液体的工具和供应品,请参阅专门出版物, NENG2500, "卡特彼勒代理商工具目录"。

按照本地法规和条例处置所有液体。


在液压油中不得存在空气。 系统中的空气会妨碍制动器发挥完整的功用。

行车制动器

  1. 把机器移到坚硬、水平、干燥且无碎屑的表面。

  1. 安装转向机架锁。

  1. 设置停车制动器。

  1. 检查转向系统和制动系统的液压油箱里的油位。 在过程期间,保持液压油箱充满油。

    行车制动器上的标准排气螺钉

    (1) 排气螺钉

  1. 将一根软管连接到排气螺钉 (1) 上。 将软管的另一端置于一个透明容器中。

  1. 起动发动机并在低怠速下运转。

  1. 打开排气螺钉 (1) ,使油可流过软管。 踩下制动踏板,直到软管中流出的油不再含有气泡。

  1. 关闭排气螺钉。 对每个行车制动器重复此过程,但同一时间仅对一个行车制动器进行排气。

  1. 加注液压油箱至正确油位。

  1. 如果行车制动器在工作时显得松软,再次执行此程序。

停车制动器

  1. 轮胎前后都塞上木质挡块。

  1. 起动发动机,使油压达到切断压力。 关闭发动机。

    停车制动器的排气螺钉

    (2) 排气螺钉

  1. 将一根软管连接到位于停车制动器壳体一侧的排气螺钉 (2) 上。 将软管的另一端置于一个透明容器中。

  1. 慢慢打开排气螺钉 (2) ,使油可流过软管。 使油流出,直到油中不再有气泡。 关闭排气螺钉。
