The Chelsea 267XBFJW-M5AK or 267XBFJWM5AK is a 267 Series constant mesh power take-off built on a 10-bolt mounting pattern for Allison automatic transmissions. Output is through a 1-1/4" round shaft with key, and the unit delivers 56+ HP output power with shaft power rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM. The 267 Series exceeds the torque capacity of a 6-bolt PTO while providing the tighter sealing of a 10-bolt pattern, making it a proven choice for refuse trucks, snow and ice equipment, and yard jockey trucks running load-sensing or variable displacement piston pumps. The 360-degree rotatable flange eases installation where clearance is tight. Call us to confirm proper fit for your application.
