ABSTRACT:
A pivot assembly formed by driving an oversized pivot shaft through first and second self-lubricating flanged bushings. The bushing in the static part of the assembly has a smaller inside diameter than the bushing in the rotating part. Installation of the shaft removes a substantial portion of the wear layer on the first bushing so as to form a tight, non-rotating fit therewith, and a lesser portion of the wear layer on the second bushing so as to form a tight, rotating fit therewith.
