Wheel end play setting device
First Claim
1. A method of adjustably setting wheel bearing end play on a wheel mounted by bearings on an axle comprising the following steps:
- mounting an automatic bearing end play take-up device on a wheel, said device having a movable portion in axially aligned contact with end of the wheel axle, said take-up device having indicator means for measuring the relative movement between said device and said axle end;
tightening a wheel bearing adjusting nut until the wheel bearings are tight;
actuating said device to take up bearing end play;
reading said indicator means to determine an initial reading;
backing off the wheel bearing adjusting nut to an indicator means reading corresponding to the desired amount of end play for proper bearing operation;
locking the adjusting nut in position; and
removing the device.

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.

5. An end play take-up and measuring device for a vehicle wheel mounted by a pair of bearings on an outboard end of a vehicle axle comprising:
-
a base plate; means for mounting said base plate in fixed position on said vehicle wheel; a linear actuator having a housing mounted on said base plate, said linear actuator having a movable rod disposed to axially engage said end of said vehicle axle; means for selectively actuating said linear actuator to pull said vehicle wheel in an outboard direction relative to said vehicle axle; and an indicator means operatively associated with said device for indicating relative movement of said axle relative to said wheel. - View Dependent Claims (6, 7)

8. In combination with a vehicle wheel mounted by a pair of bearings on a vehicle axle, said axle including a wheel end play adjusting means, a wheel end play take-up and setting device comprising:
-
a base plate mounted on said wheel; a pneumatic actuator mounted on said base plate and having a movable rod disposed in an engaging position with said axle, said actuator being disposed upon actuation to continuously and automatically maintain the position of said wheel at the outboardmost position on said axle permitted by said end play adjusting means; and an indicator means for measuring relative position of said wheel on said axle, whereupon the measurement of said wheel in a no-end-play position and in an adjusted-end-play position can be read on said indicator and differenced to indicate the actual end play provided in said adjusted-end-play position. - View Dependent Claims (9, 10, 11)
