  1. 用钢丝棉去除轴 (6) 上的沉积物和腐蚀。

    注: 不要使用会在泵轴上留下明显划痕的砂纸。

  2. 检查轴的碳精密封区域。 除非该区域的点蚀和腐蚀仍可为冷却液在橡胶轴和泵轴之间提供流动的通道,否则请更换轴。 管轴上该区域的光面表示已在轴上旋转碳精密封。 安装新的密封件之前,请在抛光区域使用细砂纸。

  3. 使用工具 (C) 清洁轴 (6) 和壳体内的密封件沉头孔。

  4. 将清洁的水放在陶瓷密封 (9) 的 O 形密封圈上。 使用工具 (B) 固定壳体内的陶瓷密封。 安装陶瓷环,使光面朝向碳精密封。

  5. 将碳精密封 (8) 浸在清洁的水中。 将碳精密封 (8) 安装在轴 (6) 上。 使用工具 (A) 将碳精密封推到轴上。 推动碳精密封,直到表面接触到陶瓷密封的表面。

  6. 将弹簧 (7) 放在轴 (6) 上的合适位置。

  7. 将叶轮 (3) 放在轴上的合适位置。 安装螺栓 (4) 和垫圈 (5)。

  8. 将螺栓 (4) 拧紧至扭矩为 360 ± 50 N·m (265 ± 35 lb ft)。 用锤子敲击螺栓头。 再次拧紧螺栓。 重复这一步骤,直至扭矩不再变化。

  9. 在壳体上安装新 O 形密封圈 (2)。 将皂液涂在 O 形密封圈上。

  10. 在水泵上安装壳体 (1)。 确保壳体的方向正确。

  11. 向冷却系统加注冷却液到正确的液位。 请参阅操作和维护手册。
