ABSTRACT:
The disclosure illustrates a fixture permitting the adjustment of a stop which limits the upward travel of a unit type fuel injector plunger. The fixture comprises parallel rails having cross bars for clamping the injector to be adjusted with a given preload. An upper cross bar receives a displaceable rod adapted to be received in a socket in the injector for depressing the plunger. An arm having a given weight at its free end is pivotally mounted to the upper cross arm. The arm is pivoted downward to depress the plunger to its bottom-most position. A dial gauge indicates linear displacement of the rod and the plunger to a desired upper limit of travel where the stop is positioned. The predetermined weight at the end of the arm permits repeatable checking of the adjustment.
