The Chelsea 267 Series Power Take-Off, part number 267SBFJP-M5XY or 267SBFJPM5XY, is a 10-bolt constant mesh PTO designed specifically for Allison automatic transmissions. It delivers intermittent torque in the 301-400 lb-ft range (up to 335 lb-ft -- verify against your application) and shaft power of 32 HP at 500 RPM or 64 HP at 1,000 RPM. The 1-1/4" round output shaft with keyway suits hydraulic pump connections common on yard jockey trucks, snow and ice trucks, and small refuse vehicles. The 267 Series exceeds the torque capacity of a 6-bolt PTO while offering tighter 10-bolt sealing, and the SuperTorque gear option adds up to 20% more torque capacity when needed. Available flange outputs include 360-degree rotatable flanges for clearance-critical installations. Call us to confirm proper fit for your application.
The Chelsea 267 Series is suited for aerial, military, refuse, snow and ice, and yard jockey truck applications. Common uses include variable displacement piston pumps on small refuse trucks and snow plow trucks. Wet spline or greaseable shaft options help extend PTO and pump shaft service life. The SuperTorque gear option provides up to 20% more torque capacity than a standard 267 Series unit. Continuous operation is supported with a 30% de-rating applied.
