The Chelsea 489XFAHX-A5XX 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, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, reducing both installation time and potential leak paths. This unit features wire/cable mechanical shift, a 1-1/4" round keyed output shaft, and tapered bearings for greater load-bearing capability compared to needle-bearing designs. The 489 Series shares internal parts with the Chelsea 442 Series and delivers up to 250 lb-ft torque capacity, with intermittent torque ratings from 201 to 300 lb-ft. Available from Pro Gear and Transmission.
