The Chelsea 489XFBGX-W3XK is an 8-bolt mechanical shift Power Take-Off from the Chelsea 489 Series, designed for most manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for 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. Strong tapered bearings replace needle bearings for greater load-bearing capability. Output is through a 1-1/4" round keyed shaft. Available with no-pressure or pressure lube configurations.
