The Chelsea 489QFMEX-56RJ is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths and cutting installation time. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP, with a 1-1/4" round keyed output shaft. Wire/cable mechanical shift operation is standard. Internal parts are common to the Chelsea 442 Series. Available from Pro Gear and Transmission.
