开始:

  1. 将发动机连接到 Caterpillar 电子技师(Cat ET)上后再从发动机上拆下 DPF。 将发动机连接到 Cat ET 上后,执行灰分维修测试。 此测试为手动再生。 继续工作前,让 DPF 充分冷却。

    ------ WARNING! ------

    高温发动机部件可能导致灼伤。 进行发动机保养之前让发动机和部件冷却下来。


    ------ WARNING! ------

    在处理用过的柴油微粒滤清器或催化转化器消声器时,请配戴护目镜、手套、防护服以及经过职业安全与健康管理局(NIOSH)批准的 P95 或 N95 半面式防尘面罩。 否则可能造成人身伤害。

  1. 在卡箍组件 (1) 的两侧做出识别标记 (B) ,以便于安装。

  1. 在柴油微粒滤清器 (3) 上做出识别标记 (C) ,以便于安装。 识别标记 (C) 用来显示废气在柴油微粒滤清器内的流向。

  1. 松开卡箍组件 (1) 后向柴油微粒滤清器 (3) 中心的方向重新定位卡箍组件。 上紧卡箍组件 (1) 。

    注: 不要让任何物体接触内部的柴油微粒滤芯。 不要晃动或撞击滤清器组件。

  1. 将工具 (A) 安装到柴油微粒滤清器 (3) 上。 柴油微粒滤清器 (3) 的重量约为 27 kg (60 lb)。

  1. 松开卡箍组件 (2) 后拆下柴油微粒滤清器 (3) 。

安装步骤

  1. 按相反顺序安装柴油微粒滤清器 (3) 。

    1. 安装新卡箍组件 (1) 。 利用手动工具将卡箍组件 (1) 上紧到 50 ± 2.5 N·m (37 ± 2 lb ft) 的扭矩。
