开始:

  1. 安装车斗固定销。 请参阅拆解和组装, "销(车斗固定)- 拆卸和安装"。

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

在工作温度下,转向液压油箱是热的,而且有压力。 热油能造成烫伤。

为了避免发生可能的人身伤害,先释放转向系统中的压力,然后再断开或拆卸液压管路或部件。

只有当发动机停机,且加注口盖足以冷却可以直接用手去抓取时才可以拆卸加注口盖。



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。


注: 将盖和塞安装在全部孔口上,以免污垢或碎屑进入系统。 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。 这将防止脏污进入内部机构。

  1. 通过缓慢下压制动器卸压阀释放转向油箱中的压力。 安全阀位于转向油箱的顶部。

  2. 将转向油箱中的液压油排入合适的容器中,以便存放或进行处置。 转向油箱的容量为 40 L (11 US gal)。 请参阅操作和保养手册, "转向系统油 – 更换"。
