The Chelsea 267SBFJW-M3RY or 267SBFJWM3RY is a 10-bolt constant mesh Power Take-Off Assembly from the Chelsea 267 Series, designed to fit Allison automatic transmissions. The 1-1/4" round output shaft with keyway delivers up to 335 lb-ft (454 Nm) intermittent torque, with shaft power rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM. Output power exceeds 56 HP. The 267 Series exceeds the torque capacity of a 6-bolt PTO while providing tighter sealing through its 10-bolt mounting pattern. Chelsea's 360-degree rotatable flange improves clearance in tight installations. Wet spline lubrication is available to extend PTO and pump shaft service life. Common applications in this series include snow plow trucks, small refuse trucks, and yard jockey trucks. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 267 Series is available in five speed ratios and multiple output configurations, including SAE B and SAE C pump flanges, ISO 7652 pump flange, and driveline outputs. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series unit. This series is suited for aerial, refuse, snow and ice, military, and yard jockey applications. Part number 267SBFJW-M3RY may also be referenced as SP267SBFJW-M3RY in some catalog listings.
