The Chelsea 489GRAHX-A5RY or 489GRAHXA5RY is a Power Take-Off unit from Chelsea's 489 Series, designed for 8-bolt manual transmission openings on applications such as Eaton Fuller, Mack, and Tremec transmissions. The integral 8-bolt one-piece cast iron housing bolts directly to the transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. This unit uses a wire/cable mechanical shift and features a 1-1/4" keyed round output shaft. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP. Tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your application.
