1U-5470 发动机压力表总成
(1) 压力指示器
(2) 零位调整螺钉
(3) 压力指示器
(4) 测压口
(5) 压力指示器

此工具总成具有用于读取燃油歧管压力的压力表。 此工具总成附带一本专门说明书, GMGO8907。

测试准备工作 - 燃油歧管和输油泵压力

------ 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。



注意

不要让脏物进入燃油系统。 彻底清洁要断开的燃油系统部件的周围区域。 在所有断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。

(12) 燃油歧管燃油出口(过滤燃油)
(13) 输油泵燃油进口(未经过滤燃油)

  1. 关闭发动机。

  2. 从燃油滤清器壳体盖的弯头上拆下压力传感器 (10) 和 (11)。

  3. 从燃油滤清器壳体盖上拆下压力传感器弯头。

  4. 在 (10) 和 (11) 的端口位置上安装 5P-5528 过渡衬套。

  5. 1U-5470 发动机压力总成连接到过渡衬套。 参考图 3。 使用随 发动机压力总成一起提供的接头和尼龙管来连接过渡衬套。

    在压力传感器 (10) 的位置上可以检查来自燃油输油泵的燃油压力。 在压力传感器 (11) 的位置上可以检查供应至燃油歧管的燃油压力。 燃油滤清器压差可通过压力传感器 (10 )的位置和螺塞 (11) 的位置之间的燃油压力差来进行检查。
