Abstract
An inductor for inductively heating the valve seat of an engine component includes non-magnetic spacer pads on the inductor coil which engage the valve seat surface to establish the inductive coupling gap, and a centering nose which enters the valve stem bore and coacts with a universal coupling between the inductor and the inductor frame to provide concentricity between the valve seat and the core and to accommodate angular variations between the valve seat and the inductor frame.
