272RGKUP-B3RK Chelsea 272 Series 6-Bolt Hot Shift PTO

The Chelsea 272RGKUP-B3RK or 272RGKUPB3RK is a 272 Series 6-bolt hot shift power take-off built for medium-duty work in towing and recovery, aerial, construction, and water truck applications. It mounts via a 6-bolt pattern and delivers a 1-1/4" round output shaft with a 5/16" key. Shift is pneumatic or PowerShift (pneumatic/hydraulic), with an integral air control valve included. Intermittent torque rating runs 201-300 lb-ft (401-500 Nm); continuous torque capability reaches 300 lb-ft, though actual ratings vary by application. Shaft power at 1,000 RPM is 57 HP (43 kW). The 272 Series consolidates the older 230, 231, 236, 238, 270, and 271 lines into a single, updated unit with rotatable flanges. Call us to confirm proper fit for your transmission and application.
