拆卸步骤


注意

保持所有零件清洁无杂质。

杂质会造成快速磨损和缩短部件寿命。



注意

在检验、保养、测试、调整及维修产品时,务必留心,确保液体盛装在容器中。 在打开任何腔室或拆解任何储有液体的部件之前,要准备好用合适的容器收集液体。

按照本地法规和指令处置所有液体。


注: 塞住并盖好所有开口和管组件。

  1. 断开涡轮增压器进口和出口的空气软管。

  2. 如果涡轮增压器有一个远程废气旁通阀电磁阀,从涡轮增压器的执行器上断开软管。 从涡轮增压器的供油管组件上断开涡轮增压器电磁阀的软管组件。 用夹子固定软管组件。

  3. 断开排气管。

  4. 如果涡轮增压器有排气弯管,应拆卸排气弯管。 请参阅拆解和组装, "排气弯管 - 拆卸和安装"。
