A clutch assembly includes an input member, an output member, and clutch plates connected to the input and output members which are driven into drive engagement with one another when the clutch is engaged to connect the output member for rotation with the input member. The clutch plates carried on the input member are mounted on a separate clutch plate carrying member, which is machined before installation on the input member to thereby facilitate manufacture and assembly of the device. A fluid pressure responsive piston operates the clutch plates, and has an outer diameter slidingly and sealingly engaged with the wall to bore of the housing of the input or driving member, and its inner diameter slidingly engaged with an annular retainer which is mounted for rotation with the input member. A pair of roller bearings mount the input or driving member on a fixed spindle and on the output member, and bypass passages are provided around the bearings to assure that fluid pressure can be relieved from oil seals sealing the bore and the bearings within the housing defined by the input or driving member.
