如何装配喷油泵?
(1)将套筒从泵体的上端装入泵体,注意套简侧面的长方孔对准泵体上的定位螺丝孔,将紫铜垫圈放入定位螺丝孔，用定位螺丝固定，这时螺丝不要上得太紧。(2)将泵体位置平放,先装入齿条、齿圈,注意对准它们的记号;再装入柱塞,也要对准柱塞凸肩和齿.圈切口，上的记号,然后装入弹簧上座、油泵弹簧、弹簧下座、导程简;最后将导程筒压入泵体,在泵体的底部有一小孔，用一个铁钉插入小孔,挡住导程筒放入卡环，取出铁钉。(3)将泵体正置,将齿条拉到停车的位置,观察柱塞.上的直槽是否对准泵体.上的回油孔，以判断油泵内部零件的记号是否对准。记号对正后,放入出油阀座、出油阀、紫铜垫圈、出油阀弹簧,.上紧紧座。(4)安装放气螺钉和进油接头,不要忘记加垫圈，上紧定位螺丝。
