The Chelsea 267 Series Power Take-Off, part number 267XGFJW-M3AK or 267XGFJWM3AK, is a 10-bolt constant mesh PTO built for Allison automatic transmissions. It delivers shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM, with an intermittent torque rating in the 301-400 lb-ft range (verify actual rating on Chelsea application pages). The output shaft is a 1-1/4" round with keyway. Rotatable flanges allow 360-degree positioning to clear tight installations, and the wet spline option extends service life on both the PTO and pump shaft. The SuperTorque gear option adds up to 20% more torque capacity versus a standard 267 Series unit. Common applications include snow plow trucks, small refuse trucks, and yard jockey trucks. Call us to confirm proper fit for your transmission and pump configuration.

The Chelsea 267 Series is available in multiple output configurations including SAE B pump flange, SAE C pump flange, ISO 7652 pump flange, and driveline output. The 267 Series exceeds the torque capacity of a standard 6-bolt PTO while maintaining the tighter sealing of a 10-bolt pattern. Markets served include refuse, snow and ice removal, aerial, and military applications.
