The Chelsea 221ZLDAX-A5XK or 221ZLDAXA5XK is a 221 Series Power Take-Off assembly built for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. It mounts via a 6-bolt pattern and shifts by wire/cable mechanical actuation. The 1-1/4" round output shaft with keyway delivers up to 250 lb-ft (339 Nm) intermittent torque, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Compatible transmissions include Allison, Eaton/Fuller, Volvo/Mack, Hino, and others. The cast iron housing accepts either a standard or low-profile configuration. Greaseable pump shafts help reduce spline fretting and corrosion over time. Available from Pro Gear and Transmission, call us to confirm proper fit for your application.
