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: 为确定单体喷油器的可再用性，请参阅专门说明书, SEHS9787, "Caterpillar 3114、3116 和 3126 机械式单体喷油器的测试步骤"。

- 使用工具 (A) 松开单体喷油器。 旋转单体喷油器，以使喷油器齿条 (3) 与喷油控制连杆 (2) 分离。
注: 不要撬动喷油器压紧支架。 否则单体喷油器可能出现损坏。 单体喷油器在齿条的相对侧有一个槽口。 该槽口用于撬松单体喷油器。 未压缩弹簧时，一些喷油器齿条可自由移动。 没有略微压缩喷油器弹簧时不要移动喷油器齿条。 否则单体喷油器可能出现损坏。
- 拆下单体喷油器。 确保两个 O 形密封圈在单体喷油器上。
