The Chelsea 221XCAHP-W3XD or 221XCAHPW3XD is a 6-bolt Power Take-Off assembly from the Chelsea 221 Series, built for low-speed, heavy-duty applications such as dump trucks, tow and recovery, and aerial equipment. It uses a wire/cable mechanical shift and mounts to Allison, Eaton/Fuller, Volvo/Mack, Hino, and other transmission types. The 1-1/4" round output shaft with keyway delivers up to 250 lb-ft intermittent torque (verify actual rating on the application pages). Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The cast iron housing is available in standard or low-profile configuration, and greaseable pump shafts help resist spline fretting and corrosion.
