拆卸步骤
开始:
- 释放液压系统压力。 请参阅拆解和组装, "系统压力 - 释放"。
注: 清洁度是一项重要的因素。 拆卸步骤开始之前，应彻底清洁部件外部。 这将有助于防止污垢进入部件的内部。
注: 为便于安装，在所有管路、所有软管、所有线束组件及所有管上做出识别标记。 插接好所有线路、软管和管路。 这将有助于防止液体泄漏和防止污染物进入系统。

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。 |

滚热的油或液压油的压力会对人员造成伤害。 发动机停机之后，液压油的压力仍会保留在液压系统里。 对液压系统进行维修之前，如果不事先释放压力，可能会造成严重伤害。 卸下液压系统的部件或管路时，确保所有的作业机具都已降到地面上，而且液压油温度已冷。 只能在发动机停机，并且加注口盖冷却到可以用徒手触摸时才能卸下加注口盖。 |
- 断开线束组件 (7) 和软管组件 (6) 。
