The Chelsea 489QFMEX-66XK is an 489 Series Power Take-Off unit engineered for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. This unit uses a wire/cable mechanical shift and features a 1-1/4" round keyed output shaft. Tapered bearings replace needle bearings for greater load-bearing capability. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 48 HP at 1,000 RPM. Common internal parts with the Chelsea 442 Series simplify service.
