The Chelsea 221 Series Power Take-Off Assembly, part number 221ZEAHP-W4XQ or 221ZEAHPW4XQ, is built for low-speed, heavy-duty applications such as dump trucks, tow and recovery, and aerial equipment. It mounts via a 6-bolt pattern and shifts through a wire/cable mechanical mechanism. The 1-1/4" round output shaft (with key) delivers up to 250 lb-ft intermittent torque, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, Hino, and others. The cast iron housing features tapered cone output bearings for high load capacity, and greaseable pump shafts help reduce spline fretting and corrosion. Available in standard or low-profile housing configurations. Call us to confirm proper fit for your application.
