The Chelsea 221XEAHP-A3XD or 221XEAHPA3XD is a 6-bolt Power Take-Off assembly from the Chelsea 221 Series, built for low-speed, heavy-duty service on dump trucks, tow and recovery units, and aerial equipment. Shift type is wire/cable mechanical. The 1-1/4" round output shaft with key accepts a range of hydraulic pump connections. Output power runs 46-55 HP (31-40 kW), with shaft power rated at 24 HP (500 RPM) and 48 HP (1000 RPM). Intermittent torque is rated up to 250 lb-ft (339 Nm) - check application pages for actual torque ratings specific to your setup. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, Hino, and others. A cast iron housing and tapered cone output bearings provide durability over needle-bearing designs. Greaseable pump shafts reduce spline fretting and corrosion. Call us to confirm proper fit for your application.
