C175-20 BXR

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

渗漏或溅溢到热表面或电气部件上的燃油会引起失火。 为防止可能的伤害,当更换燃油滤清器或油水分离器滤芯时,要将起动开关断开。 应立即将溅溢的燃油清除干净。


维修粗滤器前,确保发动机停机。

任何时候如果发生了以下情况,请更换燃油粗滤器滤芯:

  • 燃油滤清器差压计登记 103 kPa (15 psi)。

  • 燃油滤清器已经使用了1200个工时数。

  • 燃油传送泵的进压低于 40 kPa (5.8 psi )。

更换燃油滤清器滤芯


注意

不要让脏物进入燃油系统。 彻底清洁将要拆开的燃油系统部件的周围区域。 在拆开的燃油系统部件上安放适当的盖。

    注意

    使用适当的容器来盛接可能溅出的燃油。 立即清理所有溅溢的燃油。


  1. 打开排放阀 (1) ,将滤清器中的油排放到适当的容器中。

  1. 拆下旧滤清器。

  1. 在新的燃油滤清器垫片上涂抹干净的柴油。


    注意

    安装燃油滤清器之前不要向燃油滤清器中注入燃油。 否则燃油不会被过滤并可能受污染。 污染的燃油会加速燃油系统零件的磨损。


  1. 把新燃油滤清器旋装到燃油滤清器底座上,直到密封垫接触到底座。 用手拧紧燃油滤清器一整圈。 不要过分拧紧滤清器。 使用滤清器上的旋转刻度标记作为适当拧紧的指示。
