The Chelsea 267 Series Power Take-Off, part number 267XBFJW-M5RY or 267XBFJWM5RY, is a 10-bolt constant mesh PTO built for Allison automatic transmissions. It delivers up to 335 lb-ft (454 Nm) intermittent torque and shaft power of 32 HP at 500 RPM or 64 HP at 1,000 RPM. The output shaft is a 1-1/4" round with key. Designed for continuous-duty mobile applications, it suits variable displacement piston pumps on refuse trucks, snow and ice equipment, yard jockey trucks, and aerial units. The 267 Series exceeds the torque capacity of a 6-bolt PTO while offering tighter sealing with the 10-bolt mounting pattern. Available with Chelsea's 360-degree rotatable flange and the SuperTorque option for up to 20% additional torque capacity. Call us to confirm proper fit for your application.
