Method and apparatus for precision axial free end play adjustment of tapered bearings
First Claim
1. A method of adjusting a bearing assembly on a threaded axle spindle between a wheel hub and a threaded spindle nut, comprising:
- a) over-tightening the spindle nut against the bearing assembly until there is no linear movement between them, b) identify the dimensional linear position of the over-tightened wheel hub on the spindle, c) loosening the over-tightened spindle nut by a selected amount, and d) re-tightening the spindle nut to the identified dimensional linear position of the wheel hub on the spindle.

Abstract
The adjustment of axial free play between the ends of a wheel bearing assembly and a wheel hub and spindle nut of the wheel assembly is achieved by first over-tightening the spindle nut against the wheel hub; secondly, identifying by an indicator gauge between the wheel hub and spindle nut the amount of axial travel of the over-tightened hub on the spindle; thirdly, loosening the spindle nut until an indicator between the hub and spindle nut substantially matches a specified amount of linear travel of the loosened hub; and finally re-tightening the spindle nut by rotating the latter the same axial amount that the hub had traveled after loosening the spindle nut.

3. A system for adjusting a bearing assembly on a threaded axle spindle between a wheel hub and a threaded spindle nut, comprising:
-
a) circumferentially spaced indicia marks on one of the spindle and spindle nut, graduated to relate to the pitch of threads on the spindle and spindle nut, and index means on the other of the spindle and spindle nut arranged for registry with the indicia marks, and b) a calibrated linear indicator member and associated contact member one mounted on the wheel hub and the other on the spindle. - View Dependent Claims (4, 5)
