The Chelsea 680XQAHX-M3XY or 680XQAHXM3XY 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, which gives it strong load-bearing capability and a high torque rating suited to demanding work like pneumatic blowers, dump trucks, and refuse vehicles. The series covers Eaton/Fuller, Mack, Volvo, Daimler/Detroit, and other 8-bolt manual transmission platforms, and includes a deep mount housing option for Mack applications. Output options in the 680 Series span SAE A, SAE B, and other flange and driveline configurations, with a space-saving air shift cover for maximum underbody clearance.
