The Chelsea 267 Series Power Take-Off, part number 267XGFJP-M5RK or 267XGFJPM5RK, is a 10-bolt constant mesh PTO designed for Allison automatic transmissions. It delivers intermittent torque in the 301-400 lb-ft range (check application pages for actual ratings) and shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM. The output shaft is a 1-1/4" round with key, suited for load-sensing pump applications on yard jockey trucks, snow and ice vehicles, and small refuse trucks. Chelsea's 360-degree rotatable flange design helps where clearance is tight. Wet spline or greaseable shaft options extend PTO and pump shaft service life. Call us to confirm proper fit for your transmission and pump configuration.
The Chelsea 267 Series is available with multiple output types including SAE B pump flange, SAE C pump flange, and ISO 7652 pump flange, as well as driveline outputs. The series supports continuous operation with a 30% de-rating. SuperTorque gears are available as an option and provide up to 20% more torque capacity than a standard 267 Series unit. Common applications include snow plow trucks, small refuse trucks, and yard jockey trucks. Aerial and military market configurations are also produced within the 267 Series line.
