The Chelsea 272GBAJX-13XD is a 6-bolt hot shift power take-off from the Chelsea 272 Series. This medium-duty PTO supports intermittent torque ratings from 201 to 300 lb-ft (401-500 Nm) and is compatible with pneumatic or hydraulic shift operation. The 272 Series consolidates the earlier 230, 231, 236, 238, 270, and 271 series into a single platform, offering nine speed ratios and eighteen shift options. An integral air control valve is included. Direct-mount configurations are available with optional wet-spline technology for extended service life, and driveshaft output configurations support the Smart-Start option for high-torque startup conditions. The 272 Series serves aerial, construction, water truck, and towing and recovery applications.

Additional Information
The Chelsea 272 Series consolidates six earlier PTO lines, including the 230, 231, 236, 238, 270, and 271 series, into a single medium-duty platform. Rotatable flanges allow flexible installation. The Smart-Start option addresses high-torque startup conditions common in towing, recovery, and aerial lift applications. The wet-spline output option reduces wear on both PTO and pump shafts during continuous operation. Typical markets include aerial work platforms, construction equipment, water trucks, towing and recovery, material handling, and defense.
