The Chelsea 267XMFJP-M5AZ or 267XMFJPM5AZ is a 10-bolt, constant mesh Power Take-Off from the Chelsea 267 Series, engineered specifically for Allison automatic transmissions. It delivers up to 335 lb-ft (454 Nm) intermittent torque and shaft power of 32 HP at 500 RPM or 64 HP at 1,000 RPM. Output is through a 1-1/4" round shaft with key. The 267 Series exceeds the torque capacity of a standard 6-bolt PTO while using a tighter 10-bolt sealing pattern. Rotatable flanges allow 360-degree positioning for clearance, and the SuperTorque option adds up to 20% more torque capacity when your application demands it. Common fits include refuse trucks, snow and ice removal equipment, yard jockey trucks, and aerial units. Call us to confirm proper fit for your specific transmission and pump setup.
