A device for restricting the flow of lubricant from a locomotive traction motor gear case and along an armature drive shaft of the traction motor and into the drive shaft\s bearing mounting assembly, portions of which extend into the gear case. The device may also restrict lubricant flow into a return drain port of the drive shaft\s bearing mounting assembly as a result of gear generated splash within the case.

A device for use with a rotatable shaft having a gear on an end of said shaft wherein said shaft projects axially outwardly of a bearing mounting assembly having a mounting plate with a shaft bore therein through which said shaft projects, and wherein said gear on said shaft is spaced axially from said bearing mounting assembly comprising, a base for nesting against said mounting plate between said gear and said mounting plate, said base having an opening therein through which said shaft may project and having at least one mounting hole therein, means carried by said base for reducing lubricant flow between said gear and said bearing mounting assembly, and securing means for attaching said base to said mounting plate, said securing means extending through said mounting hole including integrally connected top shoulder and bottom shoulders spaced apart from one another on opposite sides of said hole and defining a recessed groove with a connecting bottom wall therebetween extending through said mounting hole of said base, said recessed groove defined between said shoulders being of a width greater than the thickness of said base adjacent said securing means with said bottom shoulder projecting slightly above said mounting plate to space said base above said mounting plate to allow said base to move without substantial binding against said shoulders and against said mounting plate so as to accommodate differences in thermal expansion and contraction between said base and said mounting plate.
