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.
