The Chelsea 272MGAJP-D3RK is a 272 Series hot shift power take-off built on a 6-bolt mounting pattern. The 272 Series consolidates multiple earlier medium-duty PTO lines into a single platform, offering up to 300 lb-ft of intermittent torque and continuous-duty torque capability. Shift options include pneumatic and hydraulic actuation, and the series comes with an integral air control valve as standard. Direct-mount outputs are available with optional Wet-Spline technology for extended PTO and pump shaft life, while driveshaft output configurations include the Smart-Start option for high-torque start-up conditions. Common application markets include aerial work, construction equipment, towing and recovery, and water trucks. Pro Gear and Transmission carries this genuine Chelsea unit.
