Abstract:
A method and apparatus for measuring stem nut wear in a valve having a threaded valve stem that is positioned to engage the threads of a stem nut. In a preferred embodiment, a tool is mounted on the stem nut, wherein the tool rotates when the stem nut rotates. The tool indicates a measurement of stem nut rotation. An indicator indicates stem movement. The stem nut is rotated and the amount of percent wear is observed. Rotation continues until the stem begins to move. The tool provides a reading when the stem begins to move that indicates an amount of stem nut wear.
