The Chelsea 489DCMBX-56RK or 489DCMBX56RK is an 8-bolt Power Take-Off from the Chelsea 489 Series, designed to mount directly to manual transmissions with an 8-bolt PTO aperture, including Eaton Fuller, Mack, and Tremec gearboxes. The integral one-piece cast iron housing bolts to the transmission opening without an adapter plate, eliminating a potential leak path. The 489 Series delivers an intermittent torque rating of 201-300 lb-ft and uses tapered bearings for increased load-bearing capability compared to needle-bearing designs. Shift type is wire/cable mechanical. Output is via a 1-1/4" round keyed shaft. Call us to confirm proper fit for your application.
