The Chelsea 221REAJX-A3XR or 221REAJXA3XR is a 6-bolt power take-off assembly from Chelsea's 221 Series, built around a cast iron housing with tapered cone output bearings for demanding low-speed, heavy-duty service. Output is through a 1-1/4" round shaft with key, driven by a wire/cable mechanical shift. Intermittent torque is rated at 250 lb-ft (339 Nm); shaft power reaches 48 HP at 1,000 RPM and 24 HP at 500 RPM. Transmission compatibility spans Allison, Eaton/Fuller, Volvo/Mack, and Hino platforms. The 221 Series is available in a standard or low-profile housing, and greaseable pump shafts reduce spline fretting and corrosion over time. Call us to confirm proper fit for your application.
