The Chelsea 489 Series Power Take-Off, part number 489XQAHX-H5RK or 489XQAHXH5RK, is designed for 8-bolt manual transmission applications including Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. This unit uses wire/cable mechanical shift and features tapered bearings for greater load-bearing capability compared to needle-bearing designs. The 489 Series shares internal parts with the Chelsea 442 Series and delivers an intermittent torque rating of 201-300 lb-ft. Output is through a 1-1/4-inch round keyed shaft. Call us to confirm proper fit for your specific transmission and application.
