The Chelsea 272NBHVP-V3RF or 272NBHVPV3RF is a 272 Series hot-shift, 6-bolt power take-off built for medium-duty applications. It mounts via a 6-bolt pattern and shifts pneumatically or through a PowerShift pneumatic/hydraulic system, with an integral air control valve included. The output shaft is a 1-1/4" round shaft with a 5/16" key. Continuous torque capability reaches 300 lb-ft (407 Nm); intermittent torque is rated in the 201-300 lb-ft (401-500 Nm) range. At 1,000 RPM the shaft delivers 57 HP (43 kW). Compatible transmission families include Allison, Eaton/Fuller, Ford, Aisin, Volvo/Mack, RAM, and others. The 272 Series consolidates earlier Chelsea 230, 231, 236, 238, 270, and 271 Series PTOs into a single platform. Call us to confirm proper fit for your application.
