    弹簧压缩零件如果安装不当,会伤害人体。

    为避免伤害,遵照出版的装配程序,并穿上保护装备。


  1. 以与泵体组件 (9)的轴承孔的中心线成45 ± 15度角对齐套筒轴承 (8)的接头。 用工具 (A)将套筒轴承 (8)安装到机油泵体组件 (9)中。 套筒轴承必须在齿轮孔 1.5 ± 0.5 mm (0.06 ± 0.02 in) 以下。

  2. 以距离泵盖组件表面上部 6.0 ± 0.5 mm (0.24 ± 0.02 in)将孔的定位销 (16)安装到泵盖组件 (4)中。

  3. 以与泵盖组件 (4)的轴承孔的中心线成45 ± 15 度角对齐套筒轴承 (5)的接头。 用工具 (A)将套筒轴承 (5)安装到泵盖组件 (4)中。 套筒轴承应处于泵盖组件表面下方 1.5 ± 0.5 mm (0.06 ± 0.02 in)

  4. 将干净的发动机油涂抹在泵驱动轴组件 (7)和惰轮轴组件 (6)上。 将泵驱动轴组件和惰轮轴组件安装在机油泵体组件 (9)中。 将泵盖组件 (4)置于机油泵体组件上,然后安装螺栓 (10)。

  5. 以距离盖组件表面上部 6.0 ± 1.0 mm (0.24 ± 0.04 inch)将定位销安装到泵盖组件 (2)中。 将密封垫 (3)和泵盖组件 (2)置于机油泵体组件 (9)上。 安装螺栓 (1)。

    注: 在组装后发动机机油泵必须能转动自如。 用手转动发动机机油泵。

  6. 将干净的发动机油涂抹在减压滑阀 (15)上。 将减压滑阀 (15)和弹簧 (14)安装在机油泵体组件上。 安装密封垫 (13)、安全阀 (12)和螺栓 (11)。

结束:

  1. 安装发动机机油泵。 请参阅拆解和组装, "发动机机油泵 - 安装"。
