The Chelsea 221 Series Power Take-Off Assembly, part number 221XEAHX-A3XK or 221XEAHXA3XK, is a 6-bolt mounted PTO built for low-speed, heavy-duty work on tow and recovery trucks, dump trucks, and aerial equipment. It uses a wire/cable mechanical shift and accepts a 1-1/4" round output shaft with key. Rated for intermittent torque up to 250 lb-ft (339 Nm) - verify actual ratings on the Chelsea application pages for your specific configuration - and output power of 46-55 HP (31-40 kW), with shaft power of 24 HP at 500 RPM and 48 HP at 1000 RPM. Compatible with Allison, Eaton/Fuller, Volvo/Mack, Hino, and other transmission manufacturers. A cast iron housing and tapered cone output bearings provide load-bearing capability beyond needle-bearing designs. The standard housing and available low-profile housing give flexibility where clearance is tight. Greaseable pump shafts help reduce spline fretting and corrosion over time.
