The Chelsea 489XQAHX-A3RK is a Chelsea 489 Series Power Take-Off (PTO) built for 8-bolt manual transmission openings found on Eaton Fuller, Mack, Tremec, and Eaton Endurant transmissions. The integral one-piece cast iron housing bolts directly to the 8-bolt aperture, eliminating the adapter plate and the extra leak path that comes with it. This 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. Strong tapered bearings replace needle bearings for greater load capacity. Internal parts are common with the Chelsea 442 Series. Call us to confirm proper fit for your application.
