Abstract

An improved compact oil pump drive arrangement for an internal combustion engine having an auxiliary shaft that is driven by the crankshaft. The oil pump is driven by an oil pump drive shaft that is disposed between the auxiliary shaft and the crankshaft by a helical gear arrangement. The auxiliary drive shaft is also driven by a helical gear arrangement, and the helical gears on the auxiliary drive shaft are of appropriate hands so as to balance the axial thrusts on the auxiliary drive shaft.
