The Chelsea 267XBFJP-M5AF or 267XBFJPM5AF is a 10-bolt, constant mesh power take-off assembly from the Chelsea 267 Series, engineered to mount on Allison and compatible automatic transmissions. It delivers an intermittent torque rating of 335 lb-ft (454 Nm) and shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM, with output power exceeding 56 HP. The output shaft is a 1-1/4" round shaft with keyway. The 267 Series exceeds the torque capacity of a 6-bolt PTO while offering tighter sealing with the 10-bolt mounting pattern. Chelsea developed this series in collaboration with Allison engineers, making it a natural match for variable displacement piston pump applications on refuse, snow and ice, and yard jockey trucks. A genuine Chelsea part, sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
