The Chelsea 489QFMEX-56XD or 489QFMEX56XD 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 integral 8-bolt cast iron housing bolts directly to the transmission opening without an adapter plate, eliminating a potential leak path. This unit shifts via wire/cable mechanical actuation and features a 1-1/4" round keyed output shaft. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers 46-55 HP output. Strong tapered bearings replace needle bearings for greater load-bearing capability.
