Claim 8:
9. A method for conducting a subterranean operation, the method comprising:
engaging a tubular with a spinner;
rotating a drive gear, with the drive gear being coupled to the spinner via one or more other gears;
rotating the spinner in response to rotating the drive gear, wherein rotating the spinner comprises engaging teeth of the drive gear with the one or more other gears and rotating the one or more other gears in response to engaging the teeth with the one or more other gears and rotating the drive gear;
rotating the tubular in response to rotating the spinner;
counting, via an encoder, the teeth of the drive gear as the teeth pass through a sensing field of a proximity sensor;
calculating, via a rig controller, estimated revolutions of the tubular based on an actual number of teeth counted while the tubular is being threaded into a second tubular by the spinner;
comparing the estimated revolutions of the tubular to expected revolutions of the tubular; and
determining a wear status of the spinner based on the comparing.
