The Chelsea 489QFMEX-56AZ 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 requiring an adapter plate. The one-piece cast iron housing bolts straight to the 8-bolt transmission opening, eliminating an adapter plate and reducing potential leak paths. The 489 Series delivers an intermittent torque rating of 201-300 lb-ft and output power of 46-55 HP, with a wire/cable mechanical shift and a 1-1/4" round keyed output shaft. Strong tapered bearings replace needle bearings for improved load capacity. Sold by Pro Gear and Transmission.
