The Chelsea 267 Series Power Take-Off Assembly, part number 267XMFJP-M3GH or 267XMFJPM3GH, is a 10-bolt constant mesh PTO engineered specifically 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, making it well-suited for variable displacement piston pumps on refuse trucks, snow and ice vehicles, and yard jockey applications. The 1-1/4" round output shaft with keyway feeds hydraulic pumps directly, while Chelsea's 360-degree rotatable flange design simplifies installation in tight chassis layouts. Available with wet spline lubrication to extend PTO and pump shaft service life. A genuine Chelsea part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 267 Series is designed for mobile applications requiring continuous hydraulic power. Common installations include small refuse trucks, snow plow trucks, and yard jockey trucks. The series supports five available speed ratios and multiple output types, including SAE B and SAE C pump flanges. The SuperTorque option delivers up to 20% more torque capacity than a standard 267 Series unit. Wet spline lubrication is available to reduce wear on both the PTO output shaft and the mating pump shaft. The 10-bolt pattern provides tighter sealing compared to a 6-bolt mounting. Continuous operation is supported with a 30% de-rating applied.
