Chelsea 489GHAHX-A3RB or 489GHAHXA3RB is an 8-bolt power take-off assembly from the Chelsea 489 Series, designed to mount directly to most manual transmissions including Eaton Fuller, Mack, and Tremec without requiring an adapter plate. The integral one-piece cast iron housing eliminates the adapter plate and its associated leak path. This unit uses a wire/cable mechanical shift and delivers up to 24 HP at 500 RPM or 48 HP at 1,000 RPM through a 1-1/4" round output shaft. Intermittent torque capacity for the 489 Series runs 201-300 lb-ft; continuous ratings are de-rated 30% (verify actual torque on Chelsea application pages). Internal parts are common to the Chelsea 442 Series, making service and parts sourcing straightforward. Call us to confirm proper fit for your transmission and application.
