开始:

  1. 拆下电子单体喷油器。


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. 将冷却液从冷却系统中排入合适的容器,以便保存或弃置。 请参阅操作和保养手册, "冷却系统冷却液 - 更换"。

  4. 将 O 形密封圈 (2) 和 (3) 从电子单体喷油器套筒 (1) 上拆下。

安装步骤


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。


  1. 使用工具 (B) 来清理电子单体喷油器的缸盖里的孔。


    注意

    确保电子控制单体喷油器套筒和缸盖孔洁净,无其它油渍、杂质和密封剂残留物。

  2. 将 O 形密封圈 (2) 和 (3) 安装在电子单体喷油器套筒 (1) 上。

    注: 请勿将工具 (E) 涂抹到缸盖表面。 仅在电子单体喷油器套筒上涂抹工具 (E)。

  3. 将工具 (E) 涂抹在电子单体喷油器套筒 (1) 接触面有标记 "X" 的一面上。

  4. 用清洁的发动机机油润滑 O 形密封圈 (2)。

  5. 将工具 (C) 拧入电子单体喷油器套筒 (1) 的螺纹。

  6. 将工具 (C) 和电子单体喷油器套筒安置在缸盖中。 一定要小心操作,不要损坏电子单体喷油器套筒上的 O 形密封圈。

  7. 使用工具 (D) 和锤子将电子单体喷油器套筒 (1) 安装在缸盖中。


    注意

    确保电子控制单体喷油器套筒正确放入缸盖中。 如果电子控制单体喷油器套筒已正确放入缸盖孔中,那么,工具就会鸣响。


  8. 拆下工具 (D) 和工具 (C)。 使用清洁的毛巾擦去多余的工具 (E)。

  9. 向冷却系统加注冷却液。 请参阅操作和保养, "加注容量"以了解冷却系统容量。

结束:

  1. 安装电子单体喷油器。
