注意

在检查、保养、测试、调整及维修产品时,请小心确保盛接油液。 在打开任何舱室或拆卸任何含有油液的部件前,请准备好盛接液体用的适当容器。

有关收集和盛接 Cat® 产品油液的合适工具和用品,请参阅专门出版物, PERJ1017, "代理商维修工具目录"。

按照本地法规和要求处置所有油液。


------ 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。

简介

从内部将排油和吸油回路连接到风扇泵。 因此,通过使用排放口作为空气排放管路,使机油从液压油箱通过吸油管路进入泵壳体。

注: 以下情况时,将需要此排气过程:

  • 更换风扇泵。

  • 更换其他液压部件后,液压油油位低于最低油位。

  • 释放液压油箱内部的压力。

步骤

    (1) 排放管接头

  1. 加注液压油箱到压力表上的正确位置。

  2. 将连接器软管连接到风扇泵侧的排放管接头 (1)。

  3. 机油从连接器软管中流出后,拆下连接器软管。

操作步骤

  1. 加注液压油箱到压力表上的正确位置。

  2. 拆下风扇泵侧的排放管接头 (1)。

  3. 机油从端口流出后,安装管接头 (1)。
