The Chelsea 442 Series Power Take-Off Assembly, part number 442ZUFNX-W5RB or 442ZUFNXW5RB, is a 6-bolt mount PTO built for light-to-medium duty vocational applications including dump trucks, tow trucks, and service trucks. This unit runs an air shift actuator, a 0.391:1 gear ratio, and a 1-1/4" round standard output shaft. Mounting uses standard metric studs. The no-pressure-lube configuration (designation X) means no external pressure lube circuit is required. 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 across demanding duty cycles.
