This unit features wire/cable mechanical shift, a 1-1/4" round keyed output shaft, and tapered bearings for increased load-bearing capability compared to needle-bearing designs. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP, with eleven internal speed ratios available across the series. A genuine Chelsea part, sold by Pro Gear and Transmission.
