Abstract
A clutch is disclosed having an input shaft and an output shaft and having alternate pairs of discs interfitting with each other. Half of the discs being attached to the input shaft and half to the output shaft. The discs are knurled on one side in a grooved pattern. The knurling is deeper at the inner radius than at the outer radius so that there is a major restriction to oil flow from the inner radius to the outer radius. The restriction of the grooves insures that the grooves are completely filled with oil during operation of the clutch.
