The Chelsea 489XRAHX-A3GE is an 8-bolt Power Take-Off from the Chelsea 489 Series, designed to mount directly to most manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing bolts to the 8-bolt transmission opening and delivers the same torque capacity as the 442 Series, rated at an intermittent torque of 201-300 lb-ft. Shift type is wire/cable mechanical. Output is via a 1-1/4" round keyed shaft, with series output power rated at 46-55 HP. Strong tapered bearings replace needle bearings for greater load-bearing capability. Available from Pro Gear and Transmission.
