The Chelsea 272GCHVW-B5RK or 272GCHVWB5RK is a 272 Series hot-shift power take-off built for medium-duty work trucks across towing and recovery, aerial, construction, and water truck applications. It mounts via a 6-bolt pattern and shifts pneumatically or via PowerShift (pneumatic/hydraulic), with an integral air control valve included. The output shaft is a 1-1/4" round shaft with a 5/16" key. Continuous torque capacity reaches 300 lb-ft (407 Nm); intermittent torque is rated at 201-300 lb-ft (401-500 Nm). Output power exceeds 56 HP (41-50 kW). The 272 Series replaces and consolidates Chelsea's earlier 230, 231, 236, 238, 270, and 271 series PTOs into a single, compatible platform.
