The Chelsea 221XEAHX-A3XD or 221XEAHXA3XD is a 6-bolt Power Take-Off assembly from the 221 Series, built for low-speed, heavy-duty applications such as dump trucks, tow and recovery, and aerial equipment. It uses wire/cable mechanical shift and delivers an intermittent torque rating of 250 lb-ft (339 Nm) - verify your exact application torque on the Chelsea application pages. Output power reaches 48 HP at 1,000 RPM and 24 HP at 500 RPM. The 1-1/4" round output shaft with keyway is compatible with transmissions from Allison, Eaton/Fuller, Volvo/Mack, and Hino. A cast iron housing with tapered cone output bearings provides greater load-bearing capability than needle-bearing designs. Greaseable pump shafts help reduce spline fretting and corrosion over time. Call us to confirm proper fit for your transmission and application.
