The Chelsea 489 Series Power Take-Off, part number 489GRAHX-S5SQ or 489GRAHXS5SQ, mounts directly to 8-bolt manual transmission openings found on Eaton Fuller, Mack, Tremec, and Eaton Endurant gearboxes. The integral one-piece cast iron housing eliminates the need for an adapter plate, reducing both installation time and potential leak paths. This unit uses a wire/cable mechanical shift and delivers intermittent torque in the 201-300 lb-ft range, with output power of 46-55 HP. Strong tapered bearings replace needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your application.
