The Chelsea 267 Series Power Take-Off, part number 267SGFJP-M5AF or 267SGFJPM5AF, is a 10-bolt constant mesh PTO designed to fit Allison automatic transmissions. It delivers up to 335 lb-ft intermittent torque and output power of 56+ HP, with shaft power rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM. The 1-1/4" round output shaft with keyway suits variable displacement piston pumps commonly used on refuse trucks, snow and ice removal rigs, and yard jockey trucks. Chelsea's 360-degree rotatable flanges improve installation clearance, and the wet spline shaft option extends PTO and pump shaft service life. The SuperTorque gear option adds up to 20% more torque capacity over the standard 267 Series configuration. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 267 Series is available with 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 the standard 267 Series build. Wet spline lubrication (W designation) or greaseable shaft options are available to extend service intervals. Typical applications include snow plow trucks, small refuse trucks, and yard jockey trucks requiring continuous load-sensing pump operation.
