The Chelsea 267 Series Power Take-Off Assembly, part number 267XDFJP-M5GH or 267XDFJPM5GH, is a 10-bolt constant mesh PTO engineered to fit Allison automatic transmissions. It delivers over 56 HP of output power, with shaft power rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM. The intermittent torque rating falls in the 301-400 lb-ft range; check the Chelsea application pages for the specific torque rating for your installation. The 1-1/4" round output shaft includes a keyway. Chelsea's 360-degree rotatable flange design makes clearance fit easier in tight installations. The SuperTorque gear option adds up to 20% more torque capacity over a standard 267 Series. This unit is well-suited to refuse trucks, snow and ice trucks, and yard jockey truck applications. Call us to confirm proper fit for your specific transmission configuration.

The Chelsea 267 Series is available in five speed ratios and multiple output configurations, including SAE B and SAE C pump flanges and driveline outputs. The wet spline and greaseable shaft options help extend the service life of both the PTO and the connected pump shaft. Continuous operation is supported with a 30% de-rating applied. Typical applications include snow plow trucks, small refuse trucks, and yard jockey trucks.
