The Chelsea 489GRAHX-W3GH or 489GRAHXW3GH is a Chelsea 489 Series Power Take-Off designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing bolts directly to the transmission opening without an adapter plate, removing a potential leak path. This unit uses 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 delivers up to 48 HP at 1,000 RPM shaft power. Strong tapered bearings replace needle bearings for greater load capacity.
