The Chelsea 489KFAHX-V3XD is an 8-bolt Power Take-Off from the Chelsea 489 Series, designed to bolt directly to 8-bolt manual transmission openings on applications such as Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths compared to multi-piece designs. The 489 Series carries an intermittent torque rating of 201 to 300 lb-ft and supports wire/cable mechanical shift actuation. Output is through a 1-1/4" round keyed shaft. Tapered bearings replace needle bearings for greater load-carrying capability. Common internal parts with the Chelsea 442 Series simplify service.
