The Chelsea 267SGFJW-M3RY or 267SGFJWM3RY is a 10-bolt constant mesh Power Take-Off from the Chelsea 267 Series, designed to fit Allison automatic transmissions. It delivers intermittent torque in the 301-400 lb-ft range, with application-specific ratings up to 335 lb-ft (454 Nm), and shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM. The output shaft is a 1-1/4" round configuration with keyway. The 267 Series exceeds the torque capacity of a 6-bolt PTO while maintaining the tighter sealing of a 10-bolt pattern, making it well-suited for load-sensing and variable displacement piston pump applications on snow and ice trucks, small refuse trucks, and yard jockey trucks. Wet spline shaft lubrication is included to extend PTO and pump shaft service life. Call us to confirm proper fit for your application.
