The Chelsea 489XFAHX-W3RD is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed for most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. This PTO uses a wire/cable mechanical shift and features a 1-1/4" round keyed output shaft. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and output power of 46-55 HP. Strong tapered bearings replace needle bearings for greater load-bearing capability. Available from Pro Gear and Transmission.
