The Chelsea 221ZEAHX-W3RA or 221ZEAHXW3RA is a 221 Series Power Take-Off assembly built for low-speed, heavy-duty vocational work including dump trucks, tow and recovery, and aerial equipment. It mounts via a 6-bolt pattern and uses wire/cable mechanical shift. The 1-1/4" round output shaft (with key) delivers up to 250 lb-ft intermittent torque and 48 HP at 1,000 RPM, or 24 HP at 500 RPM. Compatible transmissions include Allison, Eaton/Fuller, Volvo/Mack, Hino, and other manufacturers. The cast iron housing is available in standard or low-profile form, and greaseable pump shafts help prevent spline fretting and corrosion over time.
