The Chelsea 272 Series Power Take-Off Assembly, part number 272XMAJP-B3XD or 272XMAJPB3XD, is a medium-duty hot-shift PTO built on Chelsea's redesigned 272 platform. It mounts via a 6-bolt pattern and shifts pneumatically or via PowerShift (pneumatic/hydraulic). The output shaft is a 1-1/4" round shaft with a 5/16" key. Continuous torque capacity for the 272 Series 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 consolidates Chelsea's earlier 230, 231, 236, 238, 270, and 271 medium-duty PTO lines into a single, more versatile platform compatible with transmissions from Allison, Eaton/Fuller, Ford, Aisin, Volvo/Mack, and RAM.
