The Chelsea 267XMFJP-M5XK or 267XMFJPM5XK is a 10-bolt constant mesh Power Take-Off assembly from the Chelsea 267 Series, designed to fit Allison automatic transmissions. The 1-1/4" round output shaft with keyway delivers up to 335 lb-ft intermittent torque (check application pages for actual torque ratings) and shaft power of 32 HP at 500 RPM or 64 HP at 1,000 RPM. The 267 Series exceeds the torque capacity of a 6-bolt PTO while maintaining tighter sealing through the 10-bolt mounting pattern. Chelsea's 360-degree rotatable flange design helps clear tight installation spaces, and wet spline or greaseable shaft options extend service life. Suited for refuse, snow and ice, and yard jockey truck applications. Call us to confirm proper fit for your specific transmission and pump setup.
