The Chelsea 267 Series Power Take-Off, part number 267XBFJP-M3GY or 267XBFJPM3GY, is a 10-bolt constant mesh PTO engineered to mount on Allison automatic transmissions. This series delivers an intermittent torque rating of 301-400 lb-ft (401-500 Nm), with shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM, and output power exceeding 56 HP. The 1-1/4" round output shaft with keyway suits hydraulic pump drives common on yard jockey trucks, small refuse trucks, and snow and ice removal equipment. Chelsea's 360-degree rotatable flange design improves pump clearance in tight installations, and the SuperTorque option adds up to 20% more torque capacity over a standard 267 Series. Call us to confirm proper fit for your specific transmission configuration.
The Chelsea 267 Series is suited for variable displacement piston pump applications including snow plow trucks, small refuse trucks, and yard jockey trucks. The 10-bolt mounting pattern provides tighter sealing than a 6-bolt design. Continuous operation is supported with a 30% de-rating applied. The SuperTorque option delivers up to 20% more torque capacity than a standard 267 Series unit. Wet spline and greaseable shaft options help extend service life on both the PTO and the driven pump shaft.
