The Chelsea 267 Series Power Take-Off, part number 267XBFJW-M5AF or 267XBFJWM5AF, is a 10-bolt constant mesh PTO engineered to mount on Allison automatic transmissions. The output shaft is a 1-1/4" round shaft with keyway, and the unit delivers shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM, with an intermittent torque rating up to 335 lb-ft (454 Nm) - verify actual torque for your specific application. The 267 Series exceeds the torque capacity of a 6-bolt PTO while providing the tighter sealing of a 10-bolt pattern, making it well suited for variable-displacement piston pumps on refuse trucks, snow and ice equipment, and yard jockey trucks. A genuine Chelsea part sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 267 Series is available in five speed ratios and multiple output configurations, including SAE B and SAE C pump flanges and driveline outputs. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series unit. Typical applications include snow plow trucks, small refuse trucks, and yard jockey trucks.
