  • 拆下芯。 有关步骤,请参阅维修手册。

    1. 将后冷器芯倒置,以便倒掉碎屑。


      注意

      不要用高浓度的腐蚀性清洁剂来清洗芯子。 高浓度腐蚀性清洁剂会腐蚀芯子内部的金属从而引起渗漏。 只使用推荐浓度的清洗剂。


    1. 用清洁剂反向冲洗芯。

      Caterpillar 建议使用 Hydrosolv 液体清洁剂。 表 1 中列出了可在 Caterpillar 代理商处获得的 Hydrosolv 液体清洁剂。

      表 1

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

      高压空气会造成人身伤害。

      不按下面的适当步骤进行操作会造成人身伤害。 使用压缩空气时,戴防护面罩及穿防护服。

      用做清洗用途时,喷嘴处最大空气压力必须低于205 kPa (30 psi) 。


    1. 用压缩空气吹干芯。 让空气向正常流动的相反方向吹。

    1. 检查芯以确保清洁。 对芯进行压力测试。 许多配备维修用散热器的车间都能进行压力测试。 如有必要,修理后冷却器芯。

    1. 安装芯。 有关步骤,请参阅维修手册。

    有关清洁芯的更多信息,请咨询当地的 Caterpillar 代理商。
