The Chelsea 489GFAHX-A5GH 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 bolts directly to the transmission without an adapter plate, removing a potential leak path. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 48 HP at 1,000 RPM via a 1-1/4" round keyed output shaft. Shift is wire/cable mechanical. Tapered bearings replace needle bearings for stronger load-bearing capability. Available from Pro Gear and Transmission.
