ABSTRACT:
The indirectly mounted tapered roller bearings which support a pinion shaft in a differential housing are set by turning a nut at the end of the shaft down to reduce the spacing between the cones of the two bearings. Initially, the bearings exist in end play, and as the end play diminishes, the torque transmitted through the bearings from the rotating shaft to the housing is monitored. When the transmitted torque increase, signifying that the bearings have entered preload, the nut is rotated still further, through a prescribed angle relative to the shaft. Thus, the preload in the bearings is set to be a prescribed dimensional magnitude. The bearings may also be set to a prescribed condition of end play by rotating the nut in the opposite direction when the transmitted torque increases.
