The Chelsea 267XGFJW-M5XK or 267XGFJWM5XK is a 10-bolt constant mesh Power Take-Off assembly from Chelsea's 267 Series, engineered specifically for Allison automatic transmissions. It delivers shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM, with an intermittent torque rating in the 301-400 lb-ft range (check application pages for the actual rating for your configuration). The output shaft is a 1-1/4" round shaft with keyway. Rotatable flanges simplify installation in tight clearance situations, and wet spline or greaseable shaft options help extend service life on the PTO and pump shaft. The SuperTorque gear option is available for applications demanding additional power output. Typical applications include snow and ice trucks, small refuse trucks, and yard jockey trucks. Call us to confirm proper fit for your application.
