The Chelsea 489XLAHX-V3AK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to bolt directly to an 8-bolt transmission 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. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP, with a wire/cable mechanical shift and a 1-1/4" round keyed output shaft. Tapered bearings replace needle bearings for greater load-bearing capability. Available from Pro Gear and Transmission.
