The Chelsea 489GWAHX-A3GF or 489GWAHXA3GF is an 8-bolt Power Take-Off assembly from the Chelsea 489 Series, designed to mount directly to manual transmissions with an 8-bolt aperture including Eaton Fuller, Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission opening without an adapter plate, reducing potential leak paths. This unit delivers intermittent torque in the 250 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 with key and wire/cable mechanical shift are defining features of this configuration. Strong tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series. A genuine Chelsea part sold by Pro Gear and Transmission.
