The Chelsea 680ZQAHX-A3XV or 680ZQAHXA3XV is a 680 Series Power Take-Off built for medium to heavy-duty manual transmission applications with an 8-bolt PTO aperture. The 680 Series uses a cast iron housing with tapered cone bearings on the output shaft for a high intermittent torque rating in the 301-400 lb-ft range. A space-saving air shift cover maximizes clearance under the truck, and the input shaft runs tapered bearings rather than needle bearings for greater load-bearing capability. The 680 Series covers Eaton/Fuller, Volvo/Mack, Daimler/Detroit, and other transmission manufacturers. Common applications include pneumatic blowers, aerial equipment, dump trucks, fire and rescue, and refuse vehicles. Call us to confirm proper fit for your specific transmission and application.
