拆卸步骤

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、软管、导线和管子上做出识别标记。 塞住所有管路、软管和管子。 这将有助于防止液体泄漏和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! ------

热的冷却液、蒸汽和碱会造成人身伤害。

在工作温度下,发动机冷却液是热的而且处在压力下。 散热器和所有到加热器的管路或发动机中都有热的冷却液或蒸汽。 与它们的任何接触都会造成严重烫伤。

只有当发动机停机且冷却系统压力盖已经冷却到可以徒手触摸时,再慢慢拆下冷却系统压力盖以释放压力。

不要试图在冷却液还热的时候去拧紧软管接头,软管会脱落而造成灼伤。

警告:冷却系统的冷却液添加剂含碱。 应避免它与皮肤和眼睛接触。


  1. 将发动机冷却液排入合适的容器,以便保存或弃置。 请参阅操作和保养手册, "加注容量"。
