Additional Information
The Chelsea 267 Series was developed in collaboration with Allison engineers to fit the Allison World Transmission family. The 10-bolt mounting pattern exceeds the torque capacity of a standard 6-bolt PTO while providing tighter sealing. A SuperTorque option is available within the 267 Series for up to 20% additional torque capacity over the standard configuration. Typical markets include aerial, refuse, snow and ice, and military applications.Parts Manual: Chelsea 267 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
