當凸輪的凸起部分轉過去后，在彈簧力的作用下，柱塞向下運動，柱塞上部空間（稱為泵油室）產生真空度，當柱塞上端面把柱塞套上的進油孔打開后，充滿在油泵上體油道內的柴油經油孔進入泵油室，柱塞運動到下止點，進油結束

柱塞泵缸體鑲裝銅套的，可以采用更換銅套的方法安裝。首先把一組柱塞桿處徑修整到統一尺寸，再用1000#以上的砂紙拋光外徑。

柱塞泵最重要的部件是軸承，如果軸承出現游隙，則不能保證液壓泵內部三對磨擦副的正常間隙，同時也會破壞各磨擦副的靜液壓支承油膜厚度，降低柱塞泵軸承的使用壽命。據液壓泵制造廠提供的資料，軸承的平均使用壽命為10000h，超過此值就需要更換新口。拆卸下來的軸承，沒有專業檢測儀器是無法檢測出軸承的游隙的，只能采用目測，如發現滾柱表面有劃痕或變色，就必須更換。
