The Chelsea 489QUAHX-A3XD is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths and cutting mounting time. Shift type is wire/cable mechanical. The output shaft is a 1-1/4" round shaft with key. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 48 HP at 1,000 RPM on shaft power. Tapered bearings replace needle bearings for greater load-bearing capability. Sold by Pro Gear and Transmission.
