Abstract
A self piloting balance arbor for use in the dynamic balancing of gas turbine engine components having shafts extending therefrom. The arbor includes a cylindrical sleeve for receiving the shaft, and an annular flange at one end. A conical compliant member extends axially and radially inward from the flange to an end portion having two flat surfaces perpendicular to each other. Upon the application of a load to the arbor the two flat surfaces come into contact with the component, thereby correctly positioning the arbor relative to the component.
