REVERSIBLE LUBRICANT PUMP Abstract of the Disclosure A reversible lubricant pump supplies oil to one of a pair of tandem drive axles. The pump includes a housing mounted on the axle helical gear cover to receive oil from an oil sump within the axle casing and to discharge oil to various components within the drive axle assembly. A drive gear and a driven gear are mounted within the housing for rotation in either direction to pump oil from a common inlet passage to a common outlet passage. The drive gear is mounted on a pump shaft which extends from within the housing to within the axle helical gear cover and has a pump gear fixedly mounted thereon. The pump gear is driven in response to movement of an input shaft of the axle assembly to cause the pump to operate in both the forward and reverse directions. A lubricating port within the housing extends from the pump discharge to the bearing of the pump shaft to provide the pump shaft with lubrication when the drive axle assembly is operated in the forward direction.
