Abstract: A multiplate wet clutch assembly including a sealed housing adapted to be mounted on an engine flywheel and providing a sump for cooling fluid. The clutch includes a driving member and a driven member consisting of two or more clutch plates, with each clutch plate having integral fluid scooping members or diverters on its outer periphery adapted to dip into the sump and divert fluid inwardly along diagonal slots from which the fluid feeds into grooves in friction facings on the plates and then outwardly by centrifugal force. To accommodate two or more clutch plates, an adapter ring is positioned between the clutch housing and the flywheel to provide spacing for additional clutch plates and extra sump capacity for the cooling fluid.
