The Chelsea 267XDFJW-M5AK is a constant mesh Power Take-Off Assembly from Chelsea's 267 Series, engineered specifically for Allison automatic transmissions using a 10-bolt mounting pattern. The output shaft is a 1-1/4" round shaft with keyway, suited for load-sensing and variable displacement piston pump installations common on yard jockey, refuse, and snow and ice removal trucks. Intermittent torque capacity for the 267 Series ranges from 301 to 400 lb-ft, with the application pages specifying 335 lb-ft as the check rating. Shaft power output is 32 HP at 500 RPM and 64 HP at 1000 RPM. The 267 Series exceeds the torque capacity of a comparable 6-bolt PTO while maintaining tighter sealing through its 10-bolt pattern.
