The Chelsea 267 Series Power Take-Off, part number 267XBKVP-M3RB or 267XBKVPM3RB, is a 10-bolt constant mesh PTO engineered to fit Allison automatic transmissions. It delivers shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM, with an intermittent torque range of 301-400 lb-ft (check application pages for the actual torque rating for your specific configuration). The 1-1/4" round output shaft with key suits variable displacement piston pump setups common on refuse trucks, snow and ice removal vehicles, and yard jockey trucks. The 267 Series offers 360-degree rotatable flanges for clearance flexibility, wet spline or greaseable shaft options, and an available SuperTorque option delivering up to 20% more torque than the standard configuration. 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 267 Series exceeds the torque capacity of a 6-bolt PTO while providing the tighter sealing of a 10-bolt pattern. Typical applications include snow plow trucks, small refuse trucks, and yard jockey trucks requiring continuous power for load-sensing pump systems. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series build.
