The Chelsea 489 Series Power Take-Off, part number 489DFMCX-56XV or 489DFMCX56XV, is a mechanical-shift PTO built for manual transmissions with an 8-bolt mounting aperture, including Eaton Fuller, Mack, and Tremec. The integral one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate and reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power from 46 to 55 HP, with a 1-1/4" round keyed output shaft. Tapered bearings provide greater load-bearing capability than needle-bearing designs. Shift type is wire/cable mechanical. Call us to confirm proper fit for your application.
