The Chelsea 282 Series Power Take-Off Assembly, part number 282XBAJX-B5XD or 282XBAJXB5XD, is a medium-duty hot-shift PTO designed for demanding continuous-duty cycles. It mounts via an 8-bolt pattern and accepts pneumatic or PowerShift (pneumatic/hydraulic) actuation. The 1-1/4" round output shaft uses a 5/16" key and delivers up to 56 HP or 43 kW at 1,000 RPM. Intermittent torque ratings run 201-300 lb-ft (401-500 Nm); continuous torque reaches 300 lb-ft, making this unit suitable for fuel oil delivery, aerial, towing and recovery, water truck, and construction equipment applications. Compatible transmissions include Allison, Volvo/Mack, and Eaton/Fuller platforms. Call us to confirm proper fit for your truck and transmission.
The Chelsea 282 Series is engineered for aerial, construction equipment, towing and recovery, water truck, and fuel oil delivery applications. The series offers 9 speed ratios and 18 shift options. Rotatable flanges allow flexible output positioning during installation. The optional wet-spline design extends PTO and pump shaft service life on direct-mount configurations. The Smart Start feature manages engagement under high-torque conditions to reduce drivetrain shock.
