The Chelsea 489QRMEX-56XD is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed 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. Shift type is wire/cable mechanical. The output shaft is a 1-1/4" round shaft with key. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Available from Pro Gear and Transmission.
