Product Info

Chelsea® - 277 Series


Quality knows quality, that’s why Allison chose Chelsea to join their engineers in developing PTOs specifically for the Allison World Transmissions. The versatile Chelsea 277 Series Power Take-Off (PTO) exceeds the torque capacity of a 6-Bolt PTO while offering the tighter sealing of a 10-Bolt pattern. It is available in five speed ratios and multiple output types, including Chelsea’s popular 360° rotatable flange. The 277 Series also features the SuperTorque™ option which provides up to 20% more torque capacity than a standard 277 Series.
