The Chelsea 272NDHVP-G3RK or 272NDHVPG3RK is a 6-bolt hot-shift power take-off from the Chelsea 272 Series, designed for medium-duty applications where continuous-duty torque capacity and flexible mounting matter. This unit runs a 1-1/4" round output shaft with a 5/16" key and supports pneumatic shift as well as PowerShift (pneumatic/hydraulic) operation, with an integral air control valve included. Intermittent torque rating runs 201-300 lb-ft (401-500 Nm); continuous torque is rated at 300 lb-ft (407 Nm) -- verify actual rating against your specific application.
