The Chelsea 489XFAHX-V5RJ 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 standard 8-bolt transmission opening, eliminating an adapter plate and reducing potential leak paths. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 46-55 HP output. Wire/cable mechanical shift and a 1-1/4" round keyed output shaft are characteristic of this series. Strong tapered bearings replace needle bearings for greater load-bearing capability. Sold by Pro Gear and Transmission.
