The Chelsea 489 Series Power Take-Off Assembly, part number 489XQITX-A3XR or 489XQITXA3XR, bolts directly to an 8-bolt transmission opening on most manual transmissions, including Eaton/Fuller, Volvo/Mack, and others. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path compared to designs that require one. Output is delivered through a 1-1/4" round shaft with key, rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque for the 489 Series is 201-300 lb-ft (301-400 Nm); consult Chelsea application pages for continuous-duty ratings. The unit uses wire/cable mechanical shift actuation. Internal components are common to the Chelsea 442 Series, which simplifies parts sourcing and bench service. Call us to confirm proper fit for your application.
