The Chelsea 489XQAHX-A5XX 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, removing a potential leak path. The 489 Series delivers intermittent torque of 201-300 lb-ft and uses a wire/cable mechanical shift. Output is through a 1-1/4" round keyed shaft. Tapered bearings replace needle bearings for improved load capacity. Available at Pro Gear and Transmission.
