したことを特徴とする燃料噴射ポンプ。 A fuel injection pump comprising a plunger and a barrel in which the plunger is movable up and down and rotatable, and the barrel is moved up and down by a control sleeve and a roll rack to adjust the injection timing, and the control sleeve is arranged in the longitudinal direction. It has a pinion in the middle that engages with the teeth of the control rack, and the upper and lower parts have collars that contact the internal bore of the pump body and are rotationally guided, and the lower collar has a visual mark for engagement with the control rack. A notch is formed in the pump body, and the pump body has a diameter sufficient to retract the control rack in a direction parallel to its axis when inserting the control sleeve, and after adjusting the engagement with the control sleeve, the thick-walled bushing can be inserted. A fuel injection pump characterized in that a support hole is formed for supporting a control rack at a specified position.
