The Chelsea 489XRAHX-A5XK or 489XRAHXA5XK is a 489 Series Power Take-Off Assembly designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission opening, eliminating the adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical. The output shaft is a 1-1/4" round shaft with key, and output power for the 489 Series runs 46-55 HP (31-40 kW), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque rating for the series is 201-300 lb-ft (301-400 Nm); check application pages for actual torque ratings on your specific setup. Internal parts are common with the Chelsea 442 Series. Call us to confirm proper fit for your application.
