The Chelsea 442 Series Power Take-Off 442ZXFNX-A3RA or 442ZXFNXA3RA is a 6-bolt mount PTO configured with air shift engagement, a 0.391:1 gear ratio, and a 1-1/4" round standard output shaft. The mounting option uses standard mount with metric studs, and the unit runs without pressure lube. The 442 Series is built around a cast iron housing with tapered cone bearings on the output shaft, a combination that supports the series' intermittent torque rating of up to 250 lb-ft (339 Nm). Output shaft flanges rotate 360 degrees for clearance flexibility, and the output shafts are greaseable for ongoing serviceability. Typical applications in this series include dump trucks, tow trucks, service trucks, and aerial equipment. Call us to confirm proper fit for your specific transmission application.
