拆卸步骤

表 1
所需工具    
工具     零件号     零件描述     数量    
A     4C-9832     发动机翻转支架     1    
B     138-7576     连杆支架     2    

开始:

  1. 拆卸摇臂轴组件和推杆。 请参阅拆解和组装, "摇臂轴和推杆 - 拆卸"。
  2. 拆下飞轮壳体。 请参阅拆解和组装, "飞轮壳体 - 拆卸和安装"。
  3. 拆卸前壳体。 请参阅拆解和组装, "前驱动壳体 - 拆卸和安装"。
  4. 卸下活塞冷却喷嘴。 请参阅拆解和组装, "活塞冷却喷嘴 - 拆卸和安装"。


注意

当活塞和连杆被推离轴箱时,没有拆卸摇臂轴组件和推杆可能会损坏气门。

为避免损坏气门,拆卸曲轴前拆卸摇臂轴组件和推杆。



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。


  1. 使用工具 (A) 将发动机转到水平位置。 发动机可用工具 (A) 或挡块支撑。

    • 3508B 发动机的重量约为 3470 kg (7650 lb)。

    • 3512B 发动机的重量约为 5440 kg (12000 lb)。

    • 3516B 发动机的重量约为 6550 kg (14440 lb)。

    注: 如果从发动机上拆卸活塞和连杆组件,则没必要从曲轴上拆卸配重。
