ABSTRACT:
An improved fuel pump construction including a driven shaft having cams thereon for actuating a fuel pump for internal combustion engines, a driving shaft adapted to be driven by an engine proportionally to engine speed, the shafts having aligned, splined ends in close adjacency with the lead of the splines on the ends being dissimilar. A splined coupling interconnects the ends and is axially movable thereon and rotatable with the shafts. A collar rotatably receives the coupling and restrains the coupling against axial movement. An adjusting mechanism including a manually and selectively operable actuator is provided for axially adjusting the position of the collar and for holding the collar in a desired position of adjustment. By reason of the dissimilar lead between the splines, movement of the collar, and thus the coupling, will change the angular relationship between the two shafts so that precise timing can be achieved without disassembling the mechanism.
