A     138-7573     连杆支架     2    

开始:

  1. 拆下排气歧管。 请参阅拆解和组装, "排气歧管 - 拆卸和安装"。
  2. 拆下摇臂轴和推杆。 请参阅拆解和组装, "摇臂轴和推杆 - 拆卸"。
  3. 拆下进气歧管。 请参阅拆解和组装, "进气歧管 - 拆卸"。
  4. 拆下水温调节器壳体。 请参阅拆解和组装, "水温调节器- 拆卸和安装"。


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。

有关适合收集和盛接卡特彼勒产品上液体的工具及用品,参考专门出版物, NENG2500, "卡特彼勒工具和修理车间设备指南"。

按照当地法规和指令处置所有液体。


注: 3064 发动机有一个气缸盖,而 3066 发动机则有两个。

    典型实例

  1. 将工具 (A) 、吊链和适当的起吊设备安装到缸盖 (2) 上。

  1. 将缸盖 (2) 从缸体上拆下。 3066 发动机缸盖组件的重量为 32 kg (70 lb)。 3064 发动机缸盖组件的重量为 45 kg (100 lb)。

    注: 将缸盖放在不会使缸盖表面产生损失的表面上。
