The Chelsea 267SGFJP-M3XY or 267SGFJPM3XY is a 267 Series constant mesh Power Take-Off built on a 10-bolt mounting pattern to fit Allison automatic transmissions. It delivers up to 335 lb-ft (454 Nm) intermittent torque and produces 32 HP at 500 RPM and 64 HP at 1,000 RPM, with an output rating of 56+ HP. The 1-1/4" round output shaft includes a keyway for positive drive coupling. Chelsea's 267 Series exceeds the torque capacity of a 6-bolt PTO while maintaining the tighter sealing of the 10-bolt pattern, making it a practical fit for yard jockey trucks, small refuse trucks, and snow and ice applications. The rotatable flange output simplifies clearance routing, and wet spline or greaseable shaft options help extend service life on the PTO and connected pump. Call us to confirm proper fit for your specific transmission and pump configuration.
