Abstract
A wheel end play measuring device including a pneumatic actuator attached to the wheel with its rod in axial alignment with the wheel axle and an indicator associated with the actuator rod to indicate the axial end play of the wheel bearing. Adjustment of the wheel relative to the axle for setting the wheel bearings at the desired tightness is accomplished by tightening the adjustment nut to a solid condition, actuating the pneumatic cylinder to pull the wheel to the outboard limit of the end play, setting the indicator to zero, and backing off the adjustment nut until the desired end play setting is shown on the indicator.
