ABSTRACT:
A bearing lubrication system for a final drive arrangement includes a first oil supply chamber and a rotatable gear within the first chamber. A first housing, which defines the chamber, contains a passageway which connects the first oil chamber with a cavity adjacent a first bearing assembly. The cavity is in fluid communication with a second oil chamber and a second bearing assembly by way of a longitudinal bore. A steel ring member prevents lubricating fluid from flowing past the first bearing assembly and ensures a supply of fluid to the second bearing assembly.
