Abstract: To provide a surface of wear-resistant material on the start lever of a lever assembly for a fuel injection pump control apparatus, a headed bolt of hardened, wear-resistant material is punch-pressed into a plate-like portion of the lever being engaged by a positioning element so that continuous movement of the positioning element with respect to the lever will not wear out the engagement surface and thus change a preset position of the positioning element with respect to the engagement surface of the lever, while permitting the lever to be made of a material suited for its purpose without regard to the particular surface characteristics of the engagement surface with the positioning element.

Abstract: An apparatus for adjusting the delivery quantity on multi-cylinder fuel injection pumps including a drive unit and a clamping means for the injection pump in the form of an in-line pump. The pump pistons are provided with at least one control edge and are axially arranged and rotatably guided in cylinder barrels. Each piston is held in its fitting position, at least indirectly, by a flange. A mechanically activatable adjusting tool is mounted in the apparatus and operatively arranged to be driven via a control gear. The tool is force lockingly connected to an application point or engagement point on the securing flange of the injection pump or to a transmission element coupled to the securing flange or the cylinder barrel. A servo motor, preferably a stepping motor, is used to drive a control gear which effects movement of the tool.
