ABSTRACT:
A modified railroad wheel and axle assembly used to replace conventional railroad wheel and axle assemblies whereupon one end of a railroad axle assembly is machined to receive a modified railroad wheel assembly thereon. The other end of the railroad axle assembly has a conventional railroad wheel member press fit thereon in a non-rotatable condition. The invention is operable to allow one of two spaced railroad wheel members on a railroad axle assembly to be slip rotatable thereon to reduce wear and tear on a railroad wheel member and the railroad rail members on which the railroad wheel member is tracking. The modified railroad wheel assembly includes a wheel retrofit assembly having 1) a main support retainer member to be press fit on a modified end wheel support section on a railroad axle assembly; 2) a retainer washer member to be mounted about the modified end wheel support section of the railroad axle assembly and engageable with a shoulder section on the railroad axle assembly and the main support retainer section to hold the railroad wheel member therebetween; and 3) a slip bushing member mounted about a wheel retainer section on the main support retainer member and having the railroad wheel member mounted thereon to permit relative slip rotation thereon. The slip bushing member is constructed of a nylon or Teflon self-lubricating material.
