The Chelsea 221RCAJP-A3XK or 221RCAJPA3XK is a 6-bolt power take-off assembly from the Chelsea 221 Series, built for low-speed, heavy-duty vocational applications including dump trucks, tow and recovery, and aerial equipment. Shift type is wire/cable mechanical. The output shaft is a 1-1/4" round with keyway. Output power runs 46-55 HP (31-40 kW), with shaft power rated at 24 HP (500 RPM) and 48 HP (1,000 RPM). Intermittent torque is rated up to 250 lb-ft (339 Nm) -- confirm actual torque against Chelsea application pages for your specific installation. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, Hino, and others. The cast iron housing uses tapered cone output bearings for load-bearing durability, and the pump shaft is greaseable to reduce spline fretting and corrosion.
