ABSTRACT:
A timing gage for the unit injector of a diesel engine includes a timing gage sleeve adapted to encircle the extended plunger follower of an injector so as to permit its abutment against a fixed element thereof or of the engine next adjacent to the injector. The contact pin carrys with it a portion of an electrical circuit arrangement, including a timing light that is adapted for movement relative to a contact gage base, secured to the timing gage sleeve, between a closed electrical circuit connection therewith and an open electrical circuit therewith. The contact pin upon engagement with the plunger follower when at a predetermined height is then operative to effect energization of the timing light whereby to indicate proper setting of injector timing for that injector.
