The 680 Series features a cast iron housing with tapered cone bearings on both the input and output shafts, a design suited to higher-torque work such as pneumatic blowers and hydraulic pump drives. A space-saving air shift cover maximizes clearance under the truck. The series offers multiple output configurations and four internal speed ratios.
