Abstract: A power takeoff (PTO) clutch unit for connection to an engine flywheel has interleaved friction disks and center plates for transfer of power to an output shaft. A pair of anti-friction bearings support the output shaft. Actuation fluid and in some cases lubrication fluid are provided at a rotary union adjacent the bearings. A spring assembly biases the PTO to a disengaged position. Gland rings are positioned about the output shaft on either side of the rotary union to allow passage of pressurized actuating and lubricating fluid to the bearings.
