Abstract
A coupler pivot pin and retention clip assembly for a railroad car coupler adapted to pivotally connect a knuckle of the railroad car coupler to a body of the railroad car coupler. The pivot pin assembly includes a pivot pin having an elongate shank having a head at one end and a groove formed in the shank at a second end. A circular retention clip member is adapted to be selectively retained within the groove and to the shank to prevent removal of the pivot pin from the coupler. The retention clip member includes a generally circular band having a respective tab extending generally radially outwardly from each end of the band. The band is resiliently flexible from a relaxed position, wherein the band is adapted to be retained in the groove, to an expanded position, wherein the band has an enlarged diameter allowing the band to be removed from the groove and the pivot pin so that the pivot pin may be removed from the coupler, by manually pressing the first and second tabs together.
