The Chelsea 489KHAHX-V5XK is an 8-bolt Power Take-Off unit 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 eliminates the need for a separate adapter, reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range with a wire/cable mechanical shift mechanism. Output is through a 1-1/4" round keyed shaft. Tapered bearings replace needle bearings for greater load-carrying capability. Pro Gear and Transmission carries this genuine Chelsea PTO unit for utility, dump truck, and vocational equipment applications.
