Description
The Chelsea 442 Series Power Take-Off, part number 442XUKBX-W5XD or 442XUKBXW5XD, 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 with air shift actuation, a standard mount with metric studs, and a 1-1/4″ round standard output shaft. The no-pressure-lube design keeps the lubrication setup straightforward. Rotatable output flanges allow clearance adjustments without repositioning the entire assembly, and the greaseable output shaft extends service intervals. Suited for tow trucks, service trucks, dump trucks, and light-to-medium aerial applications. Call us to confirm proper fit for your transmission.
