Quality knows quality, which is why Allison chose Chelsea to join their engineers in developing PTOs specifically for the Allison World Transmissions. The versatile 267 Series is a constant mesh PTO that exceeds the torque capacity of a 6-Bolt PTO while offering the tighter sealing of a 10-Bolt pattern. The Chelsea 267 Series Power Take-Off (PTO) is an excellent choice for variable displacement piston pumps used in refuse and snow and ice removal applications. It is available in five speed ratios and multiple output types, including Chelsea’s popular 360° rotatable flange. The 267 Series also features the SuperTorque™ option which provides up to 20% more torque capacity than a standard 267 Series.
