The Chelsea 272GDHVP-G3XD or 272GDHVPG3XD is a 272 Series hot shift power take-off (PTO) assembly with 6-bolt mounting and a 1-1/4" round output shaft with 5/16" keyway. It supports both pneumatic and PowerShift (pneumatic/hydraulic) engagement and carries a continuous torque rating of 300 lb-ft (407 Nm) with an intermittent torque range of 201-300 lb-ft (401-500 Nm). Shaft power output reaches 29 HP at 500 RPM and 57 HP at 1,000 RPM. Compatible transmissions span a broad range including Allison, Eaton/Fuller, Ford, Aisin, Volvo/Mack, and RAM applications. The 272 Series consolidates earlier Chelsea medium-duty hot shift PTO lines, making this a versatile drop-in fit across towing, aerial, construction, and water truck platforms.
