The Chelsea 221XLDAX-W3XD or 221XLDAXW3XD is a 6-bolt power take-off assembly from the Chelsea 221 Series, engineered for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. It uses a wire/cable mechanical shift and mounts to transmissions from Allison, Eaton/Fuller, Volvo/Mack, Hino, and other manufacturers. The 1-1/4" round output shaft with keyway delivers up to 250 lb-ft of intermittent torque (verify actual rating on Chelsea application pages). Available in a standard cast iron housing or a special low-profile housing for tight underbody clearance. Greaseable pump shafts help combat spline fretting and corrosion over time.
