Abstract
An measurement apparatus for measuring end play of a linear actuator features a dial indicator and a primary mounting clamp. A plunger of the dial indicator is displaceable back and forth to cause an indicator needle to move about a graduated dial to reflect a measurement of said displacement. The primary mounting clamp has a clamp body configured to releasably clamp onto an output rod of said linear actuator, and a dial support body projecting outwardly from said clamp body. The dial support body is configured to the support the dial indicator thereon in a working position in which the plunger reaches axially along the output rod toward a gear housing of said linear actuator to abut against a contact surface carried on a stationary portion of the actuator relative to which the output rod undergoes displacement during operation of said actuator.
