The Chelsea 489DAMAX-56RK or 489DAMAX56RK is a Chelsea 489 Series Power Take-Off (PTO) built for 8-bolt manual transmissions, including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The 489 Series uses a one-piece cast iron housing that bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift type for this series is wire/cable mechanical. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and features tapered bearings rather than needle bearings for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your application.
