The Chelsea 489 Series Power Take-Off Assembly, part number 489XSAHX-A3AF or 489XSAHXA3AF, is a wire/cable mechanical shift PTO built around a one-piece cast iron housing that mounts directly to an 8-bolt transmission opening on compatible Eaton/Fuller, Volvo/Mack, and other manual transmissions. The integral housing eliminates the need for a separate adapter plate, reducing potential leak paths. 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, with an intermittent torque rating of 201-300 lb-ft for the series. Tapered bearings replace needle bearings for greater load capacity. Internal components are common with the Chelsea 442 Series, keeping service parts familiar. Call us to confirm proper fit for your specific transmission and application.
