The Chelsea 272MBAJP-45XD is a 272 Series hot shift power take-off assembly built on a 6-bolt mounting pattern. The 272 Series consolidates earlier Chelsea medium-duty PTO lines into a single, more capable unit rated for intermittent torque from 201 to 300 lb-ft (401-500 Nm), with output power exceeding 56 HP (41-50 kW). Shift options for the series include pneumatic (air) and hydraulic, with an integral air control valve included. The 272 Series features rotatable flanges and supports both direct-mount and driveshaft output configurations. Wet-Spline technology is available within the series for extended PTO and pump shaft life, and a Smart-Start option addresses high-torque start-up demands. Common applications include aerial, construction equipment, towing and recovery, and water trucks. Call us to confirm proper fit for your application.
