The Chelsea 442 Series Power Take-Off Assembly, part number 442XSAHX-A5XK or 442XSAHXA5XK, is a 6-bolt transmission-mount PTO built for light-to-medium duty vocational applications including dump trucks, tow trucks, and service trucks. This unit runs an air shift actuation, a 0.391:1 gear ratio, and a 1-1/4" round standard output shaft. Mounting is standard with metric studs. The no-pressure-lube configuration keeps the design simple and maintenance straightforward. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series and contribute to its long service life. Greaseable output shafts and a 360-degree rotatable output flange option improve installation flexibility in tight chassis environments.
