The Chelsea 272FPLLP-B8BD or 272FPLLPB8BD is a 272 Series hot shift power take-off assembly built for medium-duty applications including towing and recovery, aerial work, construction equipment, and water trucks. It mounts via a 6-bolt pattern and uses a pneumatic or PowerShift (pneumatic/hydraulic) shift mechanism with an integral air control valve. The 1-1/4" round output shaft accepts a 5/16" key and delivers up to 300 lb-ft continuous torque and 201-300 lb-ft intermittent torque. Shaft power output reaches 57 HP at 1,000 RPM. Rotatable flanges, a Wet-Spline option for extended shaft life, and a Smart Start option for high-torque engagement give this unit broad fitment across Ford, Allison, Eaton/Fuller, Aisin, Volvo/Mack, and RAM transmissions. Call us to confirm proper fit for your transmission and application.
