Abstract
A mechanism for advancing and retarding the injection timing of a mechanically-actuated fuel injection pump. The mechanism includes a housing having a bore slidably receivable of an advance piston which cooperates with a lever of the fuel injector timing mechanism. A light load piston also in the bore cooperates with the advance piston to permit adjustment of timing under light load conditions. A rotatable cam mechanism cooperates with a flange on the light-load piston to set the axial rest position of the light-load piston and the advance piston, and hence the datum timing of the fuel injection pump. The cam may be easily set by external adjustment.
