The Chelsea 267SDFJP-M5XD or 267SDFJPM5XD is a 10-bolt, constant mesh Power Take-Off from the Chelsea 267 Series, designed to mount on Allison automatic transmissions. It delivers an intermittent torque rating in the 301-400 lb-ft range, with 335 lb-ft cited for reference (verify actual rating for your application). Shaft power is 32 HP at 500 RPM and 64 HP at 1,000 RPM. The output shaft is a 1-1/4" round shaft with keyway. The 267 Series is well-suited to variable displacement piston pumps in refuse, snow and ice removal, and yard jockey applications. The 360-degree rotatable pump flange helps clear tight chassis packaging. Call us to confirm proper fit for your application.
The Chelsea 267 Series PTO is commonly used on snow plow trucks, small refuse trucks, and yard jockey trucks. The 267 Series exceeds the torque capacity of a 6-bolt PTO while providing the tighter sealing of a 10-bolt pattern. Output flange options across the 267 Series include SAE B, SAE C, and ISO 7652 pump flanges, plus driveline outputs. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series unit. Continuous operation is supported with a 30% de-rating applied.
