The Chelsea 489XFAHX-H3AF or 489XFAHXH3AF is a 489 Series Power Take-Off assembly designed for 8-bolt manual transmission openings, including Eaton Fuller, Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, reducing potential leak paths compared to multi-piece designs. Shift is wire/cable mechanical. The output shaft is a 1-1/4" round with key. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm); continuous ratings require a 30% de-rate, confirm actual torque requirements against Chelsea application data before installing. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common with the Chelsea 442 Series, simplifying parts sourcing. Call us to confirm proper fit for your specific transmission.
