The Chelsea 267XGFJP-M3XD or 267XGFJPM3XD is a 267 Series constant mesh power take-off built on a 10-bolt mounting pattern for Allison automatic transmissions. The output shaft is a 1-1/4" round shaft with keyway. Intermittent torque capacity for the 267 Series ranges from 301 to 400 lb-ft, with a rated figure of 335 lb-ft (verify against Chelsea application pages for your specific installation). Shaft power is rated at 32 HP at 500 RPM and 64 HP at 1000 RPM, with output power in the 56+ HP class. The 267 Series is well-suited to variable displacement piston pumps on refuse trucks, snow and ice vehicles, and yard jockey trucks. Rotatable flanges, a SuperTorque gear option, and wet spline or greaseable shaft choices are all available within the series. Call us to confirm proper fit for your application.
The Chelsea 267 Series is designed in cooperation with Allison engineers for use with Allison World Transmissions. The 267 Series exceeds the torque capacity of a 6-bolt PTO while offering the tighter sealing of a 10-bolt pattern. Typical applications include snow plow trucks, small refuse trucks, and yard jockey trucks requiring continuous power for load-sensing hydraulic pumps. Available output types across the 267 Series include SAE B pump flange, SAE C pump flange, ISO 7652 pump flange, and driveline. The series is available in five speed ratios. The SuperTorque option adds up to 20% more torque capacity over a standard 267 Series build.
