The Chelsea 489GAAHX-A3RB or 489GAAHXA3RB is a 489 Series Power Take-Off assembly designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Volvo/Mack, and other compatible units. The one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the need for an adapter plate and reducing potential leak paths. Intermittent torque capacity for this series reaches 250 lb-ft (339 Nm); continuous-duty applications require a 30% torque de-rate (verify actual ratings on the Chelsea application pages). The wire/cable mechanical shift and 1-1/4" round output shaft with keyway connect to a wide range of hydraulic pump and accessory configurations. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal components are common to the Chelsea 442 Series, which simplifies parts sourcing. Call us to confirm proper fit for your transmission.
