Abstract
An over-running clutch is provided with a cup shaped housing which axially receives a sprag clutch therein. A sprocket is connected to the housing for a low power and low speed input which is coupled to an inner race of the clutch. The outer race of the clutch is connected to an output hub. The sprocket lies within a plane that intersets the clutch assembly between a pair of outboard bearings. Sprags are received within a cavity containing lubricant, such cavity being accessible through a bore in the output adapter. Additionally, the cavity is sealed by means of a seal which may be greased by external access.
