The Chelsea 489GQAHX-A5RA is an 8-bolt Power Take-Off unit from the 489 Series, designed to bolt 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, removing a potential leak path and reducing installation time. The 489 Series carries an intermittent torque rating of 201 to 300 lb-ft and delivers up to 46 to 55 HP of output power. Wire/cable or mechanical shift types are supported, and the output is a 1-1/4" round shaft with key. Internal parts are common to the Chelsea 442 Series. Available from Pro Gear and Transmission.
