The Chelsea 489QLMEX-66XY is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing bolts to the 8-bolt transmission opening, eliminating an adapter plate and reducing potential leak paths. This unit uses a 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. Tapered bearings replace needle bearings for greater load-bearing capability. Sold by Pro Gear and Transmission.
