The Chelsea 489DLMBX-A6RK or 489DLMBX A6RK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed for most 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. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and uses wire/cable mechanical shift. Output is through a 1-1/4" round keyed shaft. Tapered bearings replace needle bearings for greater load-bearing capability. Sold by Pro Gear and Transmission.
