The Chelsea 489GRAHX-A5AZ is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to bolt 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 installation time and potential leak paths. This unit uses a wire/cable mechanical shift and features a 1-1/4" round keyed output shaft. Tapered bearings replace needle bearings for greater load-bearing capability. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Available from Pro Gear and Transmission.
