The Chelsea 680GQAHX-P3XK 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 features a cast iron housing with tapered cone bearings on the output shaft, delivering an intermittent torque rating of up to 375 lb-ft (508 Nm). A space-saving air shift cover maximizes clearance under the truck. The input shaft runs tapered bearings rather than needle bearings for greater load capacity, making this series well suited for higher-torque demand applications such as pneumatic blowers.
