The Chelsea 489DFMAX-P6XK is an 8-bolt Power Take-Off from the Chelsea 489 Series, designed to mount directly to manual transmissions including Eaton Fuller, Mack, and Tremec without the need for an adapter plate. The one-piece cast iron housing eliminates a potential leak path while delivering the same torque capacity as the 442 Series. This unit features pressure lubrication and wire/cable mechanical shift, with a 1-1/4" round keyed output shaft. The 489 Series supports intermittent torque in the 201-300 lb-ft range and output power from 46 to 55 HP. Tapered bearings replace needle bearings for greater load-bearing capability. Available from Pro Gear and Transmission.
