The Chelsea 267XDFJP-M3XE or 267XDFJPM3XE is a 267 Series constant mesh Power Take-Off built on a 10-bolt mounting pattern for Allison automatic transmissions. It delivers up to 335 lb-ft (454 Nm) intermittent torque and a shaft power output of 32 HP at 500 RPM or 64 HP at 1,000 RPM. The 1-1/4" round output shaft includes a keyway. Chelsea's 360-degree rotatable flange design gives installers flexibility when working around tight chassis clearances. The 267 Series is well matched to variable-displacement piston pumps used on snow and ice trucks, refuse trucks, and yard jockey applications. Call us to confirm proper fit for your specific transmission and pump configuration.
The Chelsea 267 Series is designed in cooperation with Allison engineers specifically for Allison World Transmissions. Typical markets include refuse, snow and ice removal, aerial, and military vehicles. Common applications include snow plow trucks, small refuse trucks, and yard jockey trucks. The 267 Series exceeds the torque capacity of a 6-bolt PTO while providing tighter sealing through its 10-bolt pattern. Five speed ratios are available within the series. Output options across the 267 Series family include SAE B pump flange, SAE C pump flange, ISO 7652 pump flange, and driveline configurations.
