气缸和气门的位置

(A) 排气门

(B) 进气门

  1. 拆下气门机构盖。 请参考拆解和组装, "气门机构盖 - 拆卸和安装"以了解正确步骤。

  1. 卸下电热塞。 请参阅拆解和组装, "电热塞 - 拆卸和安装",以了解正确的程序。

  1. 选择一个可以接近的排气摇臂。 排气摇臂可以处于任何气缸上。

  1. 使用工具 (A) 旋转曲轴,直到选定排气门的推杆端达到最大高度。 这表示液压挺杆坐在凸轮轴凸轮的基圆上。

    典型示例

    为清楚起见,图中有一个电子单体喷油器未显示。

  1. 安装工具 (B) ,使指针接触到推杆上方排气摇臂 (1) 的顶面。

  1. 使用工具 (A) 旋转曲轴,直到液压挺杆开始打开排气门。 继续旋转曲轴,直到指示器的指针移动 2.8 mm (0.11 in)。

    注: 这是 60 度的安全位置。 视液压挺杆是否回降,精确的位置可能有所不同。 随着液压挺杆继续回降,千分表上的读数可能减少。 达到 2.8 mm (0.11 in) 的值后,曲轴处于安全位置。

    注: 发动机处于安全位置后,在减振器和前壳体上做临时标记。


注意

安装摇臂轴组件前,确保曲轴位于安全位置。
