The Chelsea 272FPLLP-B8XD or 272FPLLPB8XD is a 272 Series medium-duty hot shift power take-off built on a 6-bolt mount. It uses pneumatic or PowerShift (pneumatic/hydraulic) engagement and delivers a 1-1/4" round output shaft with a 5/16" key. The 272 Series supports continuous torque up to 300 lb-ft (407 Nm) and intermittent torque in the 201-300 lb-ft range, making it suited for towing and recovery, aerial, construction, and water truck applications. Output power reaches 56+ HP at the shaft. The 272 consolidates several earlier Chelsea medium-duty PTO lines into one flexible platform.
