The Chelsea 272XCAJX-A3BD is a 6-bolt, medium-duty hot-shift power take-off assembly from Parker Chelsea's 272 Series. It mounts to transmissions from Allison, Eaton/Fuller, Ford, Aisin, Volvo/Mack, and RAM platforms. The output shaft is a 1-1/4" round with a 5/16" key. Shift is pneumatic or pneumatic/hydraulic PowerShift, and the unit includes an integral air control valve. Continuous torque capacity reaches 300 lb-ft (407 Nm); intermittent torque is rated at 201-300 lb-ft (401-500 Nm). Shaft power output is rated at 57 HP at 1,000 RPM. The 272 Series consolidates several earlier Chelsea medium-duty PTO lines into a single platform used in aerial, construction, towing and recovery, and water truck applications. Call us to confirm proper fit for your transmission and application.

Additional Information
The Chelsea 272 Series consolidates several earlier Parker Chelsea medium-duty hot-shift PTO lines, including the 230, 231, 236, 238, 270, and 271 Series, into a single platform. The 272 offers nine speed ratios and eighteen shift options. Direct-mount configurations are available with optional Wet-Spline technology for extended PTO and pump shaft service life. Driveshaft output configurations include the Smart-Start option for high-torque start-up conditions, where load inertia can spike engagement torque above steady-state levels. Typical end-use markets include aerial work platforms, towing and recovery, construction equipment, and water trucks.
