The Chelsea 272KKJKX-A5RK is a 272 Series 6-bolt hot shift power take-off, available with pneumatic or hydraulic shift and featuring an integral air control valve. The 272 Series consolidates the earlier 230, 231, 236, 238, 270, and 271 PTO lines into a single medium-duty platform rated up to 300 lb-ft intermittent torque and 56-plus HP output. Nine speed ratios and 18 shift options give this series exceptional application flexibility. Rotatable flanges, a wet-spline output option for extended pump shaft life, and a Smart-Start feature for high-torque start-up conditions are all part of the 272 Series design. Common applications include aerial, construction equipment, towing and recovery, and water trucks. Call us to confirm proper fit for your transmission and application.
