The Chelsea 489XRABX-A6XD is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, reducing mounting time and potential leak paths. This PTO uses a wire/cable mechanical shift and delivers intermittent torque in the 201-300 lb-ft range. Output is through a 1-1/4" round keyed shaft. Tapered bearings replace needle bearings for greater load-bearing capability. Available from Pro Gear and Transmission.
