The 660 Series is built around a cast iron housing with tapered cone bearings on both the input and output shafts for greater load-bearing capability compared to needle-bearing designs. The series carries an intermittent torque rating up to 375 lb-ft, making it a step up from the 442 Series when demanding applications call for more torque. Output options across the 660 Series include SAE A, SAE B, and ISO 7652 pump flanges as well as driveline configurations. Shift types available in the series include wire/cable and mechanical.
