拆卸

  1. 在催化组件外部和进口和出口部分外部贴上标签。 显示通过催化转化器的排气的流动方向。

    注: 当安装这些部分时,维持排气流动的原有方向。 这些部分必须维持排气流动的原有方向,以遵守排气标准。

    典型的催化转化器
    (1) 凸台
    (2) 带箍
    (3) 锥组件
    (4) 催化剂载体
    (5) 管塞:

  2. 拆下将锥组件连接到排气管路的螺栓。

  3. 拆下凸台。

  4. 拆下带箍。

  5. 从锥组件上分开各催化剂载体并相互分开。 拆下密封垫。 使用后应丢弃密封垫。 安装时应使用新密封垫。

  6. 如有需要,从锥组件上拆下管塞。

安裝

  1. 按与拆卸相反的顺序安装催化剂载体。

    1. 将凸台与 6 点钟位置对齐。

    2. 4C-5599 防咬合剂涂抹到管道螺塞上。 将管道螺塞 (4) 拧紧至扭矩为 29 N·m (21 lb ft)

    3. 将带箍与 12 点钟位置对齐。 拧紧带箍至扭矩为 17.0 ± 1.2 N·m (150 ± 11 lb in)
