The Chelsea 221 Series Power Take-Off Assembly, part number 221XLDAX-A5RB or 221XLDAXA5RB, is a 6-bolt mounted PTO built for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. It shifts via wire/cable mechanical actuation and delivers a 1-1/4" round output shaft with keyway. Intermittent torque capacity runs up to 250 lb-ft (339 Nm) - verify actual rating on Chelsea application pages for your specific installation. Shaft power output reaches 48 HP at 1,000 RPM. Compatible transmissions span Allison, Eaton/Fuller, Volvo/Mack, Hino, and other manufacturers. The cast iron housing uses tapered cone output bearings for strong load capacity, and greaseable pump shafts help control spline fretting and corrosion over time.
