The Chelsea 267XGFJP-M3XX or 267XGFJPM3XX is a 10-bolt, constant mesh Power Take-Off from the Chelsea 267 Series, engineered to mount on Allison automatic transmissions. It delivers an intermittent torque rating of 335 lb-ft (454 Nm), verify your application against Chelsea's application pages for your specific rating. The output shaft is a 1-1/4" round shaft with key. Shaft power is rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM, with output power exceeding 56 HP. The 267 Series exceeds the torque capacity of a 6-bolt PTO while providing tighter sealing through its 10-bolt pattern, making it well suited for load-sensing hydraulic pumps on yard jockey trucks, small refuse trucks, and snow and ice equipment. Call us to confirm proper fit for your application.
The Chelsea 267 Series is available in five speed ratios and multiple output types, including SAE B pump flange, SAE C pump flange, ISO 7652 pump flange, and driveline outputs. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series unit. Typical applications include snow plow trucks, small refuse trucks, and yard jockey trucks. The 267 Series was co-developed with Allison engineers specifically for Allison World Transmissions.
