The Chelsea 442 Series Power Take-Off Assembly, part number 442XWAHX-W3XD or 442XWAHXW3XD, is a 6-bolt mount PTO built around a cast iron housing with tapered cone bearings on the output shaft. This unit runs a 0.391:1 gear ratio, engages via air shift, and delivers power through a 1-1/4" round standard output shaft. Mounting uses standard metric studs. The no-pressure-lube design (lubricant designation X) keeps the configuration simple. The 360-degree rotatable output flange aids clearance in tight installations, and the greaseable output shaft supports extended service intervals. Typical applications include dump trucks, tow and recovery trucks, and service trucks. Call us to confirm proper fit for your transmission.
