  1. 使用工具 (G) 清洁轴组件和壳体内的沉孔。

  2. 使用 (D) 将油封 (2) 安装到水泵壳体中。 安装油封时让零件号朝向壳体。 确保油封与壳体平齐。 请勿润滑密封。

  3. 将内轴承 (5) 安装在轴组件 (8) 上。

  4. 将轴组件 (8) 安装到水泵壳体 (9) 中。

  5. 使用工具 (B) 安装挡圈 (7)。

  6. 使用工具 (E) 和合适的压具将水封 (10) 安装到轴组件 (8) 上。 安装水封时让零件号朝上。 确保水封严密地置于壳体上。 请勿润滑密封。

  7. 使用合适的夹具将叶轮 (11) 安装到轴组件 (8) 上。 叶轮应当与轴组件的顶部平齐。

  8. 使用适当的压具安装齿轮 (6)。 将齿轮安装到 29.3 mm (1.15 inch) 的高度。 使用工具 (F) 来测量尺寸 "A"。

  9. 安装轴承 (5)。 确保轴承与齿轮平齐。

  10. 安装六角垫圈 (1) 和内六角头螺栓 (4)。

  11. 安装新密封垫和盖子。 拧紧螺栓 (3) 至扭矩为 18 ± 3 N·m (13 ± 2 lb ft)
