442ZQDAX-A5XQ Chelsea PTO Assembly

The Chelsea 442 Series Power Take-Off Assembly, part number 442ZQDAX-A5XQ or 442ZQDAXA5XQ, is a 6-bolt mount PTO configured with air shift actuation, a 0.391:1 gear ratio, and a 1-1/4" round standard output shaft. The mounting uses a standard mount with metric studs, and this unit runs without pressure lubrication. Cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, which is suited for tow trucks, dump trucks, service trucks, and small aerial trucks.
