Description
The Chelsea 267SBFJP-M5AW or 267SBFJPM5AW is a 267 Series Power Take-Off built for Allison automatic transmissions. This constant mesh, 10-bolt PTO delivers up to 335 lb-ft (454 Nm) intermittent torque and is rated for continuous operation with a 30% de-rating. The 1-1/4″ round output shaft includes a keyway, and shaft power is rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM. The 267 Series exceeds the torque capacity of a 6-bolt PTO while offering tighter sealing from the 10-bolt pattern, making it a practical fit for refuse trucks, snow and ice trucks, and yard jockey trucks that run load-sensing hydraulic pumps. The Chelsea 267 Series breakdown diagram is shown below. Call us to confirm proper fit for your application.
