The Chelsea 489XQAHX-A3XL is an 8-bolt Power Take-Off (PTO) unit from the Chelsea 489 Series, designed for use with most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and uses wire/cable mechanical shift. Output is through a 1-1/4" round shaft with keyway. Tapered bearings replace needle bearings for greater load capacity. Available applications include utility trucks, dump trucks, snow and ice removal, and fire and rescue equipment. Pro Gear and Transmission carries this genuine Chelsea part.
