The Chelsea 267XMFJP-M5XR or 267XMFJPM5XR is a 10-bolt constant mesh PTO assembly from the Chelsea 267 Series, designed to fit Allison automatic transmissions. It delivers a 1-1/4" round output shaft with keyway and produces shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM, with an intermittent torque rating in the 301-400 lb-ft range (check Chelsea application pages for the exact figure for your installation). The 267 Series exceeds the torque capacity of a 6-bolt design while maintaining a tight 10-bolt sealing pattern. Output flange options include Chelsea's 360-degree rotatable flange for clearance flexibility. Common applications include snow plow trucks, small refuse trucks, and yard jockey trucks.
