The Chelsea 267 Series Power Take-Off (PTO) Assembly, part number 267XBFJW-M3AK or 267XBFJWM3AK, is a constant mesh, 10-bolt unit engineered for Allison automatic transmissions. It delivers an intermittent torque rating in the 301-400 lb-ft range (335 lb-ft per application pages) and shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM. The 1-1/4" round output shaft includes a keyway. The 10-bolt mounting pattern provides tighter sealing than a 6-bolt design, making this PTO a practical choice for yard jockey trucks, small refuse trucks, and snow and ice removal equipment. Chelsea's 360-degree rotatable flange helps resolve clearance challenges in tight installations. Call us to confirm proper fit for your application.
