Abstract
A fuel injector timing tool has an elongated tubular member on which a measurement device may be mounted. A lower end of the tubular member is attached to a base member disposed perpendicularly to the tubular member and has an open end that only partially circumscribes a plunger follower slidably disposed on a retainer element of the fuel injector. The timing tool permits ready access to an adjustable ball stud and associated lock nut mounted in a plunger actuator end of an injector rocker arm so that accurate plunger position can be set while the timing tool remains in place on the retainer element of the fuel injector.
