Abstract

Apparatus and methods for measuring backlash of a drive train of an equipment unit. The drive train may comprise an input member operatively connected with an actuator and an output member operatively connected with a work portion of the equipment unit. An example apparatus may include a sensor operable to facilitate operational measurements indicative of an operational parameter associated with the drive train, and a processing device operable to cause the actuator to move the input member until the output member moves, record the operational measurements while the actuator moves the input member, and determine a backlash of the drive train by determining a difference between the operational measurements when the input member starts to move and the operational measurements when the output member starts to move.
