282XKDAX-P5RF Chelsea PTO Assembly

The Chelsea 282XKDAX-P5RF or 282XKDAXP5RF is a medium-duty hot shift power take-off assembly from the 282 Series, designed for demanding continuous-duty cycles. It mounts via an 8-bolt pattern and accepts pneumatic or PowerShift (pneumatic/hydraulic) actuation, making it adaptable to a wide range of truck configurations from Allison, Eaton/Fuller, and Volvo/Mack transmissions. The 1-1/4" round output shaft uses a 5/16" key. The 282 Series carries continuous torque up to 300 lb-ft (407 Nm) and intermittent torque in the 201-300 lb-ft range. Shaft power output reaches 57 HP at 1,000 RPM. An optional Smart Start feature supports high-torque engagement, and optional Wet-Spline lubrication extends shaft and pump life. Common applications include aerial, towing and recovery, construction equipment, water trucks, and fuel oil delivery. Call us to confirm proper fit for your specific transmission and application.
