ABSTRACT A thrust/retaining washer for use in an overrunning clutch is formed as an annular having a single split or opening therein. The washer is formed of an acetal resin material and the split allows it to be expanded to fit over the outside of a tubular inner race and snap into a radially extending circumferential groove formed in the outer cylindrical surface of the inner race. The washer thereby prevents rollers and/or spacers from escaping from the raceway between the inner race and outer race. The washer also abuts an inwardly facing surface of an end cap secured to the outer race to provide an axial thrust surface for the clutch. Radially extending lubrication grooves are formed in both radially extending planar surfaces of the washer to provide a path for lubrication to reach the internal elements of the clutch. The grooves are formed in both surfaces to permit the washer to be installed on the inner race without first orienting the washer.
