  1. 松开卡箍 (2),然后将管组件 (1) 从选择性催化还原 (SCR) 出口 (3) 上断开。

  2. 松开卡箍 (6),然后将管组件 (7) 从 SCR 进口 (5) 上断开。

  3. 在位置 (A)、位置 (B)、位置 (C) 和位置 (D) 做临时对齐标记,以确定卡箍 (8) 和 SCR (10) 的正确位置。

  4. 将螺母 (4) 从卡箍 (8) 上拆下。 将卡箍远离 SCR 放置,以便拆下 SCR。

  5. 如有必要,拆下螺栓 (9) 和卡箍组件 (8)。

  1. 如有必要,安装卡箍组件 (8) 并松动地安装螺栓 (9)。

  2. 将 SCR (10) 定位到卡箍组件 (8) 上。 安装螺母 (4),不要拧紧。

  3. 对齐在卡箍 (8) 和 SCR (10) 的位置 (A)、 (B)、 (C) 和 (D) 上做得临时标记。

  4. 拧紧螺母 (4) 至扭矩为 22 N·m (195 lb in)

  5. 将管组件 (7) 安装到 SCR 进口 (5) 上。 安装卡箍 (6)。 拧紧卡箍至扭矩为 12 N·m (106 lb in)

  6. 将管组件 (I) 安装到 SCR 出口 (3) 上。 安装卡箍 (2)。 拧紧卡箍至扭矩为 12 N·m (106 lb in)

  7. 拧紧螺栓 (9) 至扭矩为 22 N·m (195 lb in)
