The Chelsea 489 Series Power Take-Off, part number 489GRITX-V3XK or 489GRITXV3XK, mounts to the 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating that potential leak path. Wire/cable mechanical shift drives the unit, and output is through a 1-1/4-inch round shaft with key. Intermittent torque rating for the 489 Series is 250 lb-ft (339 Nm); shaft power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal components are common with the Chelsea 442 Series, making parts sourcing straightforward. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
