The Chelsea 489GQAHX-P5RK is an 8-bolt Power Take-Off unit from the 489 Series, designed to bolt directly to 8-bolt manual transmission openings on Eaton Fuller, Mack, Tremec, and Eaton Endurant transmissions. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path and reducing installation time. Shift type is wire/cable mechanical. 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. Tapered bearings replace needle bearings for greater load capacity. Common applications include utility trucks, dump trucks, and snow and ice removal equipment. Available from Pro Gear and Transmission.
