The Chelsea 267 Series Power Take-Off, part number 267XSFJP-M3XE or 267XSFJPM3XE, is a 10-bolt constant-mesh PTO engineered for Allison automatic transmissions. It delivers intermittent torque in the 301-400 lb-ft (401-500 Nm) range, with a rated intermittent peak of 335 lb-ft (454 Nm) - check application pages for actual torque ratings for your specific installation. The output shaft is a 1-1/4" round with key. Shaft power runs 32 HP at 500 RPM and 64 HP at 1,000 RPM, with output power exceeding 56 HP. The 267 Series is a proven choice for variable-displacement piston pumps on snow and ice trucks, small refuse trucks, and yard jockey trucks. Call us to confirm proper fit for your transmission and application.
The Chelsea 267 Series is available with multiple output configurations including SAE B pump flange, SAE C pump flange, and driveline outputs. The 360-degree rotatable output flange accommodates tight engine compartment clearances. The SuperTorque option adds up to 20% more torque capacity over a standard 267 Series unit. Wet spline and greaseable shaft options help extend service life on the PTO and connected pump shaft. Common applications include snow plow trucks, small refuse trucks, and yard jockey trucks. Sold by Pro Gear and Transmission.
