The Chelsea 489QLMEX-66AZ is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to most manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing bolts to the standard 8-bolt transmission opening and eliminates a potential leak path versus adapter-plate designs. Shift type is wire/cable mechanical. Intermittent torque rating for the 489 Series runs 201 to 300 lb-ft (301 to 400 Nm), with output power of 46 to 55 HP. The 1-1/4" round keyed output shaft and tapered bearing design give this unit strong load-bearing capability. Available from Pro Gear and Transmission.
