The Chelsea 489QQMEX-66RK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to bolt directly to the 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The integral one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths and mounting time. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and up to 46-55 HP output, with wire/cable mechanical shift actuation. The round 1-1/4" keyed output shaft and tapered bearing design provide greater load-bearing capability compared to needle-bearing designs. A genuine Chelsea part from Pro Gear and Transmission.
