The Chelsea 489 Series Power Take-Off, part number 489XHAHX-P3AZ or 489XHAHXP3AZ, is a mechanical-shift PTO built for 8-bolt manual transmission openings including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, removing a potential leak path. Internal parts are common to the Chelsea 442 Series, and tapered bearings replace needle bearings for greater load capacity. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 48 HP at 1,000 RPM via a 1-1/4" round keyed output shaft. Shift type is wire/cable mechanical.
