The Chelsea 680GSAHX-A3XK or 680GSAHXA3XK is a 680 Series Power Take-Off built for 8-bolt manual transmission applications, including Eaton/Fuller, Volvo/Mack, Daimler/Detroit, and other compatible transmissions. The 680 Series uses a cast iron housing and tapered cone bearings on the output shaft, traits that support higher torque demands in applications such as pneumatic blowers, aerial trucks, dump trucks, refuse, fire and rescue, and snow and ice removal equipment. A space-saving air shift cover provides maximum clearance under the truck. The series supports continuous operation with a 30% de-rating and an intermittent torque range of 301 to 400 lb-ft.
