ABSTRACT:
A replacement for a freight car roller housing assembly in which there are two hollow wheel wells having rollers journalled therein, the wells being respectively connected by a block extending between them. The block has a vertical cylindrical passageway and one of two different kinds of thimble-shaped bushings engaged therein. One is plain and provides for the bottom end of a plug door pin to be carried therein without provision for vertical adjustment of the pin. The other is threaded and slides vertically in the passageway but can be adjusted by means of an exterior nut threaded at the upper end thereof, the latter bushing adapted to have the bottom end of a plug door pin carried therein and being adjustable vertically by rotating the nut which engages the upper side of the block.
