The Chelsea 489XWAHX-A6RK is an 8-bolt Power Take-Off from the Chelsea 489 Series, designed to mount directly to 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, eliminating a potential leak path. This unit uses a wire/cable mechanical shift and delivers up to 250 lb-ft of torque capacity, with a 1-1/4" round keyed output shaft. Strong tapered bearings replace needle bearings for greater load-bearing capability. Pro Gear and Transmission carries genuine Chelsea PTO units for vocational, utility, and municipal applications.
