拆卸備用水泵時,請參閱引擎的拆卸與組裝手冊。

葉輪和密封需定期檢查。 葉輪的使用壽命有限。 使用壽命取決於引擎操作狀況。

若泵暴露於充滿碎屑、塵土或其他研磨劑的環境,必須更常檢查組件。 若在超過 103 kPa (15 psi)的壓差下操作泵,則需檢查組件。

有好幾種不同的泵: 一些泵有一個可以插至主泵體的蓋子。 有些泵有一個將可將泵體前面部分固定在泵體主體上的夾子。 檢查泵時,必須拆下蓋子或泵體的前面部分。

有蓋子的泵

    (1) 塞子
    (2) 閂子
    (3) 蓋子

  1. 拆下塞子 (1) 然後排出泵內的水。

  2. 拆下閂子 (2) 和蓋子 (3)。

  3. 檢查 注油葉輪、注油葉輪耐磨板 和葉輪是否有磨損或損壞。 檢查泵殼是否磨損、損壞或污物堆積。

  4. 檢查泵軸和葉輪的軸是否移位。

  5. 若發現磨損或損壞,請更換已磨損或損壞的組件。 請使用適當的泵修理零件包。
