The Chelsea 442 Series PTO Assembly, part number 442GQAHX-W3XD or 442GQAHXW3XD, is a 6-bolt mount power take-off built for light-to-medium duty vocational applications including dump trucks, tow trucks, and service trucks. This unit runs air shift actuation with a 0.391:1 gear ratio and a 1-1/4" round standard output shaft. Mounting uses standard metric studs. The assembly carries no pressure lube requirement, relying on splash lubrication. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, which is rated for intermittent torque in the 250 lb-ft range across the series. The 442 Series supports thirty-six output configurations and eleven internal speed ratios, making it a versatile fit across a wide range of chassis and PTO-driven equipment.
