ABSTRACT:
A gage for indicating the runout condition of a valve seat edge formed by and between adjacent surfaces of a valve seat adjacent one end of a valve guide bore and concentric with the axis thereof, the valve guide bore accommodating an elongated pilot member that extends therefrom through the valve seat surfaces. The gage comprises a housing member adapted to be mounted on the pilot member in fixed spaced relationship from the valve seat and having a dial indicator mounted thereon at a location spaced radially from the pilot member, and a work engaging member mounted for rotatable and axial movement on the pilot member in the space between the housing and the valve seat. The dial indicator has a plunger member extending therefrom substantially parallel to the pilot member and an indicator needle operatively connected to the plunger member and movable in response to movements of the plunger member to produce a visual indication as to the position of the plunger member. The work engaging member includes an annular portion and an elongated member mounted thereon at an angle for slidable engagement with the valve seat edge whose runout is to be indicated, and a second portion including an end face slidably engageable with the plunger member whereby rotation of the work engaging member when the elongated member is engaged with the valve seat edge translates into movements of the plunger member to produce indications on the dial indicator as to the runout of the valve seat edge.
