The Chelsea 267XDFJP-M5XE or 267XDFJPM5XE is a 267 Series Power Take-Off assembly engineered for Allison automatic transmissions using a 10-bolt mounting pattern. It operates as a constant mesh PTO, making it well suited for mobile applications that demand continuous power delivery, including refuse trucks, snow and ice removal equipment, and yard jockey trucks. Intermittent torque capacity for this series ranges from 301 to 400 lb-ft (401 to 500 Nm), with a reference rating of 335 lb-ft (454 Nm); check application pages to confirm actual ratings for your specific installation. The output shaft is a 1-1/4" round shaft with key. At 1,000 RPM, shaft power is rated at 64 HP (48 kW). Chelsea's 360-degree rotatable output flange helps clear tight chassis obstructions, and the wet spline or greaseable shaft option extends both PTO and pump shaft service life. A genuine Chelsea part, available through Pro Gear and Transmission. Call us to confirm proper fit for your application.
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 SuperTorque option delivers up to 20% more torque capacity than a standard 267 Series unit. Typical markets include refuse collection, snow and ice removal, aerial work platforms, yard jockey trucks, and military applications. The 267 Series exceeds the torque capacity of a 6-bolt PTO while providing tighter sealing through its 10-bolt pattern, a combination originally developed in partnership with Allison engineers.
