The Chelsea 282GDAJX-A5RK or 282GDAJXA5RK is a 282 Series medium-duty hot-shift power take-off designed for demanding continuous-duty applications. It mounts via an 8-bolt pattern and accepts shift actuation either pneumatically or through PowerShift (pneumatic/hydraulic), giving technicians flexibility across a wide range of truck platforms, including Allison, Volvo/Mack, and Eaton/Fuller transmissions. The 1-1/4" round output shaft uses a 5/16" key drive. The 282 Series carries a continuous torque capability up to 300 lb-ft (check application pages for actual ratings) and an intermittent rating of 201-300 lb-ft (401-500 Nm). Shaft power reaches 57 HP at 1,000 RPM. Rotatable flanges, an integral air valve, and an optional Wet-Spline output make this unit at home on aerial, towing and recovery, construction, and fuel-oil delivery trucks.
