The 680 Series uses a cast iron housing with tapered cone bearings on the output shaft for increased load-bearing capability. Shift is wire/cable mechanical. The 1-1/4" round output shaft (with key option) delivers 56+ HP and handles intermittent torque up to 375 lb-ft (check application pages for actual torque ratings). Shaft power is rated at 36 HP at 500 RPM, 71 HP at 1,000 RPM, and 107 HP at 1,500 RPM. A deep-mount housing option supports Mack transmission fitment.
