Abstract
A tool (40) for selectively adjusting the relative angular positions of a fuel pump camshaft (14) and an engine main shaft to minimize the effects of gear lash and thereby optimize fuel pump timing, including a hollow first shaft (50) which is adapted to rotate with a driven gear (36) rotatably received on a tapered sleeve (26) fixed to the camshaft (14), and a second shaft (66) coaxial with and reciprocably and rotatably received within the first shaft (50) and adapted to be coupled to the camshaft (14) for rotation therewith. The second shaft (66) is coupled through a planetary gear arrangement (90-94, 97-104) to the first shaft for rotation of the main shaft. Structure is provided for adjusting the relative angular positions of the first and second shafts (50,66) and for axially translating the first shaft (50) to lock the driven camshaft gear (36) on the tapered sleeve (26).
