The Chelsea 489XCAHX-T5RK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, built for 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. This unit uses a wire/cable mechanical shift and delivers a 1-1/4" round keyed output shaft. The 489 Series shares internal parts with the Chelsea 442 Series and features tapered bearings for greater load-bearing capability over needle-bearing designs. Sold by Pro Gear and Transmission.
