拆卸步骤

表 1
所需工具    
工具     零件号     零件描述     数量    
A     183-4797     履带支重轮起重叉车     1    
FT-2930 伸出     1    
ZZ     6V-9511     螺塞     2

开始:

  1. 拆下风扇驱动泵。 请参考拆解和组装, "风扇驱动泵 - 拆卸"。

注: 清洁度是一项重要的因素。 拆解步骤开始之前,应彻底清洁部件外部。 这有助于防止尘土进入内部结构。

注: 维修数据:拆卸和安装中的工具 (ZZ) 将不在图示中列出。 显示这一工具是为了协助有经验的维修人员。


注意

在检验、保养、测试、调整及维修产品时,务必留心,确保液体盛装在容器中。 在打开任何腔室或拆解任何储有液体的部件之前,要准备好用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液体的工具及用品,参考专门出版物, NENG2500, "卡特彼勒工具和修理车间设备指南"。

按照当地法规和指令处置所有液体。


------ 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。


注: 为便于安装,在所有管路、软管、导线和管子上做出识别标记。 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。
