The Chelsea 489ZHDAX-A5RY is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to 8-bolt transmission openings on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths and cutting installation time. The 489 Series delivers intermittent torque capacity of 201-300 lb-ft and operates with a wire/cable mechanical shift. Strong tapered bearings replace needle bearings for greater load capacity, and the series supports a 1-1/4" round keyed output shaft. Internal parts are common to the Chelsea 442 Series, simplifying service and sourcing.
