Injector height measuring tool assembly

An injector height measuring assembly for use with an internal combustion engine including a fuel injector having a follower with a planar follower surface, the fuel injector being carried by a fuel injector body having a planar body surface substantially parallel to and spaced downwardly from the planar follower surface, and a pivotally mounted rocker arm having one end engaging the planar follower surface, said injector height measuring tool comprising:

• a generally cylindrical magnetic member having a generally cylindrical side surface and a planar end surface, said member having a slot therein extending from said planar end surface through said cylindrical side surface and having a size slightly greater than that of the rocker arm, the area of said planar end surface being slightly less than that portion of the planar follower surface not engaged by the pivotally mounted rocker arm, a dial micrometer gauge having a housing and an outwardly biased plunger extending therefrom and a dial carried thereby, means for holding said housing on said member so that the axes of said member and said plunger are laterally spaced apart and substantially parallel to each other, said holding means accommodating pivotal movement of said housing and said plunger about the axis of said member, in use said planar end surface magnetically engaging the planar follower surface while the portion of the rocker arm at the end thereof is located in said slot and said distal end of said plunger engaging the planar body surface, whereby said dial indicates the distance between the planar follower surface and the planar body surface, and a storage and calibration member including a generally cylindrical steel block and an annular flange protruding outwardly around said block, said block having a planar block surface and said flange having a planar flange surface, said tool being applied to said storage and calibration member for storage and for calibration such that the planar end surface engages said planar block surface and the distal end of said plunger engages said planar flange surface.
