The Chelsea 489QRMEX-66RK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to most manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The integral one-piece cast iron housing bolts to the 8-bolt transmission opening and shares internal parts with the 442 Series, giving it the same 250 lb-ft torque capacity. The 489 Series offers wire/cable mechanical shift operation and a 1-1/4" round keyed output shaft. Strong tapered bearings replace needle bearings for greater load-bearing capability. A genuine Chelsea part sold by Pro Gear and Transmission.
