开始:

  1. 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。 这有助于防止尘土进入内部结构。

注: 为了便于安装,请在所有软管组件和线束组件上做识别标记。 插好所有软管组件。 这将有助于防止液体渗漏,并有助于防止污染物进入系统。


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。


------ WARNING! ------

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。
