The Chelsea 489XLAHX-A5XY or 489XLAHXA5XY is a 489 Series Power Take-Off designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec. The integral 8-bolt cast iron housing bolts directly to the transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. This unit uses a wire/cable mechanical shift and delivers intermittent torque in the 201-300 lb-ft range, with output power from 46 to 55 HP. Strong tapered bearings replace needle bearings for greater load-bearing capability. The 489 Series shares internal parts with the Chelsea 442 Series.
