The Chelsea 489XQAHX-M5XK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to fit 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 delivers an intermittent torque rating of 201-300 lb-ft and uses wire/cable mechanical shift. Output is through a 1-1/4" round keyed shaft, with the series offering a 360-degree rotatable flange with greaseable shaft as an available option. Tapered bearings provide greater load-bearing capability compared to needle-bearing designs. A genuine Chelsea part from Pro Gear and Transmission.
