The Chelsea 221XLAHX-A3XK or 221XLAHXA3XK is a 6-bolt power take-off assembly from the Chelsea 221 Series, built for low-speed, heavy-duty applications such as dump trucks, tow and recovery, and aerial equipment. It uses a wire/cable mechanical shift and mounts to transmissions from Allison, Eaton/Fuller, Volvo/Mack, Hino, and others. The 1-1/4" round output shaft with key 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. The cast iron housing is available in standard or low-profile configurations, and greaseable pump shafts help reduce spline fretting and corrosion. Call us to confirm proper fit for your specific transmission and application.
