Abstract
An electric motor includes a housing having a bushing mounted at a first end about a shaft extending through the housing. A lubricant recirculation member formed of a one-piece assembly of unitarily joined oil throw and vibration dampening material portions is fixedly mounted on the shaft between a commutator and the bushing. The lubricant recirculation member recirculates lubricant from the bushing back toward the bushing and away from the commutator and provides a vibration dampening layer between the bushing and the commutator.
