The Chelsea 221ZLDAX-A3XK or 221ZLDAXA3XK is a 6-bolt Power Take-Off assembly from Chelsea's 221 Series, engineered for low-speed, heavy-duty applications such as dump trucks, tow and recovery, and aerial equipment. It uses wire/cable mechanical shift and mounts to transmissions from Allison, Eaton/Fuller, Volvo/Mack, Hino, and other manufacturers. The 1-1/4" round output shaft with keyway drives at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque is rated up to 250 lb-ft (339 Nm); confirm exact torque for your application. A cast iron housing with tapered cone output bearings handles higher radial loads than needle-bearing designs. Available in standard or low-profile housing configurations. Call us to confirm proper fit for your application.
