The Chelsea 267XDFJP-M3XQ or 267XDFJPM3XQ is a 267 Series Power Take-Off Assembly built on a 10-bolt mounting pattern for Allison automatic transmissions. This constant mesh PTO delivers 32 HP at 500 RPM and 64 HP at 1,000 RPM, with an intermittent torque rating in the 301-400 lb-ft range (check application pages for actual torque ratings). The output shaft is a 1-1/4" round with keyway. The 267 Series exceeds the torque capacity of a 6-bolt PTO while maintaining a tighter 10-bolt seal, making it a proven choice for refuse trucks, snow and ice removal vehicles, and yard jockey applications. Chelsea's 360-degree rotatable flange design aids clearance in tight installations, and wet spline or greaseable shaft options help extend service life on both the PTO and pump shaft. Call us to confirm proper fit for your application.

The Chelsea 267 Series is available for refuse, snow and ice removal, aerial, military, and yard jockey truck applications. Output options across the 267 Series include SAE B and SAE C pump flanges, ISO 7652 pump flange, and driveline configurations. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series unit. Wet spline lubrication (W) and pressure lube (P) options are available to match your installation requirements.
