The Chelsea 489XQABX-A6XK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The integral one-piece cast iron housing eliminates the adapter plate found on other designs, reducing potential leak paths. 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. Tapered bearings replace needle bearings for greater load-bearing capability. Shift type is wire/cable mechanical. Available from Pro Gear and Transmission.
