The Chelsea 489GLAHX-W5XD 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 integral one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths and installation time. This unit uses wire/cable mechanical shift and delivers an intermittent torque rating of 201-300 lb-ft for the 489 Series, with a 1-1/4" round keyed output shaft. Tapered bearings replace needle bearings for greater load-bearing capability. Available from Pro Gear and Transmission.
