The Chelsea 489 Series Power Take-Off Assembly, part number 489GSAHX-A3GK or 489GSAHXA3GK, is a wire/cable mechanical shift PTO built around an integral 8-bolt cast iron housing that mounts directly to the transmission opening on Eaton Fuller, Mack, Tremec, and other compatible manual transmissions. The one-piece housing eliminates the need for an adapter plate, removing a common leak path. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM or 48 HP at 1,000 RPM. The 1-1/4" round output shaft accepts a key. Tapered bearings replace needle bearings for increased load capacity, and internal parts are common to the Chelsea 442 Series. A genuine Chelsea part, sold by Pro Gear and Transmission.
