The Chelsea 221 Series Power Take-Off, part number 221XCAJP-A5RB or 221XCAJPA5RB, is a 6-bolt mounted PTO assembly with wire/cable mechanical shift. It fits transmissions from Allison, Eaton/Fuller, Volvo/Mack, Hino, and other manufacturers. The output shaft is a 1-1/4" round with keyway, and output power runs 46-55 HP (31-40 kW), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque is rated at 250 lb-ft (339 Nm) - check application pages for actual torque ratings for your specific installation. The cast iron housing mounts in standard or low-profile configuration to maximize clearance under the truck. Tapered cone output bearings handle heavy radial loads better than needle bearings. A greaseable pump shaft cuts spline fretting and corrosion over time. Built for low-speed, heavy-duty work: tow and recovery, dump trucks, aerial equipment, and vocational applications.
