7柱塞泵的检修
(1)检查柱塞有无伤痕和锈蚀现象,必要时应更换新品。
(2)检查柱塞副配合情况。将柱塞端头插人柱塞套内,倾斜约60°,若柱塞能在自身作用下地下滑为配合良好。

(4)检查出油阀副减压环带是否磨损有台阶或伤痕现象,必要时应予以更换。
(5)检查出油阀副的配合情况。用堵住出油阀下孔,用另一将出油阀轻轻向下压,当离开出油阀上端时,它能自动弹回原位,表明出油阀副密封良好,否则应更换出油阀副。A7V28MA2.0LPF00

(6)检查挺柱体。喷油泵体和挺柱体之间的间隙为0~0.03mm,如过0.2mm ,则应更换零件。
(7)检查柱塞凸缘和控制套的凹槽之间的间隙,应为0.02~0.08mm,如过0.12mm,必须更换控制套。
