The Chelsea 489XQAHX-V3XJ is a 489 Series Power Take-Off unit built for most manual transmissions, including Eaton Fuller, Mack, and Tremec, using an 8-bolt mounting aperture. The one-piece cast iron housing bolts directly to the transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and outputs 46-55 HP, with wire/cable mechanical shift and a 1-1/4" round keyed output shaft. Tapered bearings replace needle bearings for improved load-bearing capability. A genuine Chelsea part, available from Pro Gear and Transmission.
