Abstract: An overrunning clutch having structure capable of maintaining a lubricant within the overrunning clutch during operation. The overrunning clutch is provided with an outer race and an inner race with a sprag assembly positioned therebetween. The sprag assembly is provided with sidewalls which substantially prevent the escape of lubricant between the sprag assembly and the outer race. The overrunning clutch is also provided with thrust washers which substantially prevent the escape of the lubricant between the thrust washers and the outer race, while allowing injection of a lubricant through the thrust washer and over the sidewalls of the sprag assembly to lubricate the sprags during operation of the overrunning clutch.
