开始:
- 释放系统压力。 请参阅拆解和组装, "系统压力 - 释放"。
注: 在所有软管、所有软管组件、所有导线及所有管组件上作出识别标记，以便安装。 插接好所有软管组件和所有管组件。 这将有助于防止液体渗漏，并有助于防止污染物进入系统。

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。 |

保持所有零件清洁无杂质。 液压系统被异物污染会缩短液压系统部件的使用寿命。 为了避免污染物进入液压系统，总要在断开后塞住或盖住管路、管接头或软管。 罩住已解体的部件，然后在组装前正确清洁它们。 在更换任何主部件后，或特别是在部件故障后，正确清洁液压系统，以便去除全部污染物。 |
- 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。
