The Chelsea 272XBAJP-G3XR is a 272 Series hot shift power take-off assembly built on a 6-bolt mounting pattern. Part of Parker Chelsea's redesigned medium duty PTO line, the 272 Series consolidates the earlier 230, 231, 236, 238, 270, and 271 series into a single platform. Intermittent torque capability for the series reaches 300 lb-ft (401-500 Nm), with output power at 56+ HP. The series supports both pneumatic and hydraulic shift options and includes an integral air control valve. Direct mount configurations offer an optional Wet-Spline output for extended pump shaft service life, while driveshaft output configurations include Smart-Start for high-torque engagement. Typical applications span aerial work, construction equipment, water trucks, and towing and recovery. Call us to confirm proper fit for your application.
