Abstract
A small pump is connected externally of the differential housing of an axle assembly, picks up oil from the housing and pumps it through an external filter. This cools and cleans the oil and the oil may be routed to the outer bearing areas of the half shafts for lubrication. The oil flows by gravity through the axle casing back to the differential housing and, if desired, an oil cooler may be incorporated within the system.
