The Chelsea 442 Series Power Take-Off Assembly, part number 442XAAHX-A3XQ or 442XAAHXA3XQ, is a 6-bolt mount PTO built for light-to-medium duty vocational applications including dump trucks, service trucks, and tow trucks. This unit runs a 0.391:1 gear ratio with air shift actuation and mounts via standard metric studs. The 1-1/4" round standard output shaft operates without a pressure lube system, relying on greaseable output shaft fittings for maintenance. The cast iron housing pairs with tapered cone bearings on the output shaft, characteristics of the 442 Series that contribute to its torque capacity and service life.
