The Chelsea 489DRMCX-56XV or 489DRMCX56XV is a Power Take-Off assembly from the Chelsea 489 Series, engineered for 8-bolt manual transmission applications including Eaton Fuller, Mack, and Tremec gearboxes. The integral one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate that creates an additional leak path. This series uses wire/cable mechanical shift and delivers intermittent torque in the 201-300 lb-ft range, with output power from 46 to 55 HP. The 1-1/4" round keyed output shaft supports greaseable output options to reduce spline fretting and corrosion over time. Call us to confirm proper fit for your specific transmission and application.
