The Chelsea 272NBHVW-D5RY is a 272 Series hot shift power take-off assembly built on a 6-bolt mounting pattern. The 272 Series consolidates several earlier Chelsea medium-duty PTO lines into one platform, supporting intermittent torque ratings from 201 to 300 lb-ft (401-500 Nm) and output power of 56 HP or more. Shift options across the series include pneumatic (air) and hydraulic, with an integral air control valve included. The series offers rotatable flanges, wet-spline output technology for extended pump shaft life, and a Smart Start option for high-torque startup conditions. Common application markets include aerial work, towing and recovery, construction equipment, and water trucks.
