The Chelsea 272FMLLP-B8XD is a 272 Series hot shift power take-off assembly using a 6-bolt mounting configuration. The 272 Series supports intermittent torque ratings from 201 to 300 lb-ft (401-500 Nm) and delivers 56+ HP output. Shift options include pneumatic (air) or hydraulic, and the series integrates an air control valve as standard. This PTO consolidates and supersedes the earlier Chelsea 230, 231, 236, 238, 270, and 271 Series into a single platform with nine speed ratios and eighteen shift options. Rotatable flanges and a wet-spline option extend pump shaft service life. Chelsea's Smart-Start feature manages high-torque start-up conditions on demanding applications such as aerial, construction, towing and recovery, and water truck service.

Additional Information
The Chelsea 272 Series consolidates six earlier PTO series (230, 231, 236, 238, 270, and 271) into one medium-duty platform. Nine available speed ratios and eighteen shift configurations give this series broad transmission compatibility. Applications include aerial work, construction equipment, towing and recovery, and water trucks. The 272 Series is also listed for defense and material handling markets. Rotatable flanges allow output positioning to suit the installation. The optional wet-spline interface reduces wear at the PTO-to-pump connection, while the optional Smart-Start feature protects driveline components during high-torque engagement events.Parts Manual: Chelsea 272 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
