The Chelsea 267SGFJW-M5RY or 267SGFJWM5RY is a 267 Series Power Take-Off assembly built on a 10-bolt mounting pattern for Allison automatic transmissions. This constant mesh PTO runs without a shift mechanism, making it well-suited for continuous-duty mobile applications such as yard jockey trucks, small refuse trucks, and snow and ice equipment. The output shaft is a 1-1/4" round with keyway. Shaft power is rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM, with intermittent torque up to 335 lb-ft (check application pages for actual torque ratings). The 267 Series exceeds the torque capacity of a 6-bolt PTO while maintaining tighter sealing through its 10-bolt pattern. Call us to confirm proper fit for your application.
