Abstract : The patent describes an involute-spline, wear-step measurement gage comprising three coaxial and relatively rotatable splines. Springs are provided to bias a first spline in one rotary direction and the other two splines in the opposite direction when the gage has been placed on or in the spline to be measured and actuated. The first spline engages the unworn (non-drive) surface of the spline being measured and the other two splines are of different radial dimensions so that one of them engages the wear step and the other engages the unworn portion of the original involute, i.e., the form clearance, adjacent the wear step. A dial indicator arrangement registers the difference in positioning of these latter two splines in terms of the magnitude of the wear step.
