The Chelsea 221XCAJX-W3XD or 221XCAJXW3XD is a 6-bolt Power Take-Off assembly from the Chelsea 221 Series, built for low-speed, heavy-duty vocational applications including dump trucks, tow and recovery, and aerial equipment. It mounts to transmissions from Allison, Eaton/Fuller, Volvo/Mack, Hino, and other manufacturers. The wire/cable mechanical shift and 1-1/4" round output shaft with keyway suit a wide range of hydraulic pump setups. Intermittent torque capacity reaches 250 lb-ft (339 Nm); verify actual ratings on the Chelsea application pages for your specific configuration. The cast iron housing accepts either a standard or low-profile cover, and greaseable pump shafts resist spline fretting and corrosion.
