ABSTRACT:
A hole gauge arrangement is used for determining the distance of a vehicle fixture hole from a datum plane established with respect to the vehicle. The hole gauge arrangement includes a set rod with a die wheel having bores corresponding to the various sizes of fixture holes and also includes a measurement rod. By reference to a table, the desired distance from the datum plane to the fixture hole is established on the set rod and the measurement rod matched to the distance of the set rod and the hole diameter. The measurement rod is then transferred to support structure mounted in the datum plane and the distance difference, if any, between the measurement rod tip and the fixture hole is noted as an indication of dislocation.
