The Chelsea 489XFAHX-C3XK 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, Eaton Endurant, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, reducing both installation time and potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and offers wire/cable mechanical shift actuation. Output is via a 1-1/4" round keyed shaft. Tapered bearings replace needle bearings for improved load-bearing capability. Common internal parts with the Chelsea 442 Series simplify servicing. Available from Pro Gear and Transmission.
