The Chelsea 489DRMBX-56XD is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed for manual transmissions including Eaton Fuller, 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. Shift type is wire/cable mechanical. The 489 Series delivers intermittent torque of 201-300 lb-ft and output power of 46-55 HP, using tapered bearings for greater load-bearing capability compared to needle-bearing designs. Internal parts are common to the Chelsea 442 Series. Available from Pro Gear and Transmission.
