The Chelsea 267XBFJP-M5RK is a 267 Series 10-bolt Power Take-Off built for Allison automatic transmissions. It operates as a constant mesh, non-shiftable unit, making it well-suited for mobile applications that require continuous power delivery to load-sensing pumps. The 267 Series mounts on a 10-bolt pattern, offering tighter sealing than a 6-bolt PTO while exceeding its torque capacity. The series covers intermittent torque ratings in the 301-400 lb-ft range and delivers shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM. Output options across the 267 Series include SAE B and SAE C pump flanges, driveline, and multiple shaft types. Available from Pro Gear and Transmission.

Additional Information
The 267 Series was developed in cooperation with Allison engineers specifically for Allison World Transmissions. Common applications for the 267 Series include snow plow trucks, small refuse trucks, and yard jockey trucks. A SuperTorque option is available within the series, providing up to 20% additional torque capacity over a standard 267 Series unit. The RK and RJ output flange options are also available -- see Parker Product Notice PTO-PNI-275 for details.Parts Manual: Chelsea 267 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
