拆卸步骤

表 1
所需工具    
工具     零件号     零件说明     数量    
A     FT-2674     真空舱     1    
B     1U-7505     液压千斤顶     1    
C     138-7575     连杆支架     2    

开始:

  1. 释放系统压力。 请参阅拆解和组装, "系统压力 - 释放"。


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。


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。

  1. 将工具 (A) 安装到液压油箱上。 将一条供气软管连接到工具 (A) 上。 施加 276 至 414 kPa (40 至 60 psi) 的气压。 此步骤将使液压系统处于真空状态。
