The Chelsea 267 Series Power Take-Off (PTO) Assembly, part number 267XGFJW-M3RJ or 267XGFJWM3RJ, is a 10-bolt, constant mesh unit engineered for Allison automatic transmissions. The 267 Series exceeds the torque capacity of a standard 6-bolt PTO while providing tighter sealing through its 10-bolt mounting pattern. Intermittent torque is rated at 335 lb-ft (454 Nm) per application pages. The 1-1/4" round output shaft with key suits variable displacement piston pump setups common in refuse, snow and ice removal, and yard jockey applications. Shaft power output is 32 HP at 500 RPM and 64 HP at 1000 RPM. Call us to confirm proper fit for your specific transmission and pump configuration.
The Chelsea 267 Series is available in five speed ratios and multiple output types, including SAE B pump flange, SAE C pump flange, ISO 7652 pump flange, and driveline outputs. The "RJ" output flange designation on this part number reflects Chelsea's updated rotatable flange design. Typical markets served include refuse trucks, snow plow trucks, yard jockey trucks, aerial equipment, and military vehicles. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series unit.
