The Chelsea 489DQMAX-56XD or 489DQMAX56XD is a 489 Series Power Take-Off built for 8-bolt manual transmission openings, including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the transmission aperture, eliminating the need for a separate adapter plate and reducing potential leak paths. The 489 Series delivers an intermittent torque rating of 201 to 300 lb-ft (301 to 400 Nm) and a wire/cable mechanical shift configuration. Output is via a 1-1/4 inch round keyed shaft. Tapered bearings replace needle bearings for improved load capacity under demanding vocational duty. Call us to confirm proper fit for your application.
