The Chelsea 489DAMAX-P6XV is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to bolt directly to 8-bolt manual transmission openings on applications such as Eaton Fuller, Mack, and Tremec transmissions. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths and installation time. 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. Internal parts are common to the Chelsea 442 Series, and the series offers tapered bearings for load-bearing capability.
