The Chelsea 267SBFJP-M5RF or 267SBFJPM5RF is a 10-bolt, constant mesh Power Take-Off from the Chelsea 267 Series, engineered to fit Allison automatic transmissions. It delivers up to 335 lb-ft (454 Nm) intermittent torque and produces 32 HP at 500 RPM or 64 HP at 1000 RPM at the shaft. Output is a 1-1/4" round shaft with key, suitable for driving variable-displacement piston pumps, load-sensing hydraulics, and similar mobile equipment. The 267 Series exceeds the torque capacity of a standard 6-bolt PTO while offering the tighter sealing advantage of the 10-bolt bolt pattern. Rotatable flanges allow 360-degree positioning to clear frame and body obstructions. The SuperTorque gear option adds up to 20% more torque capacity over the standard configuration. Applications in the 267 Series include refuse trucks, snow and ice removal trucks, yard jockey trucks, and aerial equipment. Call us to confirm proper fit for your specific Allison transmission and pump combination.
