The Chelsea 489QLLZX-D3AZ 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. The 489 Series delivers intermittent torque of 201-300 lb-ft and output power of 46-55 HP. Shift type is wire/cable mechanical. The output shaft is a 1-1/4" round shaft with key. Tapered bearings provide greater load-bearing capability compared to needle bearing designs. Available from Pro Gear and Transmission.
