Abstract

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.
