Abstract
An oil shield for an upper tower shaft gear. The shield provides a plurality of shield members for encapsulating the upper tower shaft gear to reduce the amount of displaced oil from contacting surrounding engine components. The shield includes a first shield member adjacent a top surface of the upper tower shaft gear and a second shield member adjacent an under surface of the upper tower shaft gear which is engaged with the first shield member to enclose the upper tower shaft gear. A third shield member is positioned adjacent the second shield member. The shield members permit oil drainage in a predetermined pattern without undesirable dispersion within the engine compartments.
