A drive assembly includes a housing, upper and lower shafts, a friction pack, and a pair of meshed gears. The housing defines a receptacle containing a volume of lubricating fluid, a brake chamber with a metering orifice in a lower portion of the brake chamber, and an exit port at an upper portion of the brake chamber. The upper and lower shafts are within the housing at different elevations and configured for rotation. The friction pack is within the brake chamber and driven to rotate by the upper shaft. The pair of meshed gears is driven to rotate by one or more of the upper and lower shafts, and the gears communicate lubricating fluid from the receptacle to the lower portion of the brake chamber through the metering orifice. Rotation of the friction pack pumps lubricating fluid to the exit port at the upper portion of the brake chamber.
