The Chelsea 489DFMCX-56XD is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, built for manual transmissions including Eaton Fuller, Mack, and Tremec. The integral 8-bolt cast iron housing bolts directly to the 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-inch round shaft with key. The 489 Series carries an intermittent torque rating of 201 to 300 lb-ft and shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Available from Pro Gear and Transmission.
