The Chelsea 267 Series Power Take-Off, part number 267XDFJW-M3RJ or 267XDFJWM3RJ, is a 10-bolt constant mesh PTO engineered for Allison automatic transmissions. It delivers up to 335 lb-ft (454 Nm) intermittent torque and over 56 HP of output power, with shaft power rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM. The output shaft is a 1-1/4" round shaft with keyway. The 267 Series exceeds the torque capacity of a standard 6-bolt PTO while maintaining the tighter sealing advantage of the 10-bolt bolt pattern, making it a practical choice for refuse trucks, snow and ice removal vehicles, and yard jockey trucks requiring continuous power for load-sensing pump applications. A genuine Chelsea part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 267 Series was co-developed with Allison engineers specifically for Allison World Transmissions. The 267 Series is available with wet spline or greaseable shaft options to extend PTO and pump shaft service life. Output options across the 267 Series include SAE B and SAE C pump flanges, ISO 7652 pump flange, and driveline outputs. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series configuration. Common application markets include refuse, snow and ice removal, aerial, and military vehicles.
