The Chelsea 489QRMEX-56RE is an 8-bolt Power Take-Off from the Chelsea 489 Series, designed to mount directly to most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts to the 8-bolt transmission opening without an adapter plate, eliminating a potential leak path. Shift type is wire/cable mechanical. Output is via a 1-1/4" round keyed shaft. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and output power of 46-55 HP. Strong tapered bearings replace needle bearings for greater load-bearing capability. A genuine Chelsea part available from Pro Gear and Transmission.
