拆卸步骤

开始:

  1. 拆下凸轮轴齿轮。 请参阅拆解和组装 , "凸轮轴齿轮 - 拆卸和安装" 。

  2. 拆下曲轴前油封。 请参阅拆解和组装 , "曲轴前油封 - 拆卸"。

  3. 如有配备,拆下空气压缩机。 请参阅拆解和组装 , "空气压缩机 - 拆卸"。

  4. 拆下曲轴位置传感器。 请参阅拆解和组装 , "曲轴位置传感器 - 拆卸和安装" 。

  5. 拆下发动机支架。 请参阅拆解和组装 , "发动机支架(前部) - 拆卸和安装" 。


注意

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

在拆卸凸轮轴齿轮时,不要转动曲轴或凸轮轴。 如果在安装时没有正确调整前齿轮总成的正时,活塞与气门之间将会发生干涉,进而导致发动机损坏。
