The Chelsea 267 Series Power Take-Off, part number 267XGFJW-M5RK or 267XGFJWM5RK, is a 10-bolt constant mesh PTO designed to fit Allison automatic transmissions. It delivers a 1-1/4" round output shaft with keyway and produces shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM, with intermittent torque ratings up to 335 lb-ft (check application pages for actual torque ratings). The 267 Series exceeds the torque capacity of a 6-bolt PTO while offering tighter sealing from the 10-bolt mounting pattern. Common applications include small refuse trucks, snow plow trucks, and yard jockey trucks requiring continuous power for load-sensing pumps. The rotatable flange design allows 360-degree positioning to clear tight engine bay obstacles. 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 configurations, including SAE B pump flange, SAE C pump flange, ISO 7652 pump flange, and driveline outputs. The series supports continuous operation with a 30% de-rating. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series unit. Wet spline lubrication (W designation) and greaseable shaft options are available to extend service life on both the PTO and connected pump shaft. Typical markets include refuse, snow and ice, aerial, and military applications.
