The Chelsea 680GQAHX-V3RA or 680GQAHXV3RA is a 680 Series Power Take-Off built for 8-bolt manual transmission applications, including Eaton Fuller, Volvo/Mack, and Daimler/Detroit platforms. The 680 Series uses a cast iron housing with tapered cone bearings on the output shaft for load capacity suited to higher-torque jobs such as pneumatic blowers. The space-saving air shift cover is designed for maximum clearance under the truck. The series supports intermittent torque ratings in the 301-400 lb-ft range, with continuous operation available at a 30% de-rating. Output options span SAE A, SAE B, ISO 7652 pump flanges, and driveline configurations. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
