Abstract:
A gear box and method of providing oil through the same is provided. The gear box includes a windage tray that includes a tray having a bleed hole therein, and another tray having another second bleed hole therein. Oil is provided through the bleed holes to respective gears situated in the trays. The windage tray may also include a magnet positioned within a magnet slot of the windage tray, for removing debris from the oil. A tube may also be attached to the windage tray, which tube can include a bleed hole therein, for spraying the oil out of the tube and towards a differential, for example. The windage tray and tube can be made from molded plastic, and can be made using the same mold. The gear box housing may further define a drain in an inner side wall to provide oil to a differential bearing, for example.
