The Chelsea 489QLMEX-66RY is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The one-piece cast iron housing bolts on without an adapter plate, eliminating a potential leak path and cutting installation time. The series delivers 201-300 lb-ft intermittent torque and 46-55 HP output, with 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. Internal parts are common to the Chelsea 442 Series, making service straightforward. Available from Pro Gear and Transmission.
