The Chelsea 489 Series Power Take-Off, part number 489KFAHX-H3AF or 489KFAHXH3AF, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm); check application pages for the actual torque rating for your specific installation. Output shaft is a 1-1/4" round with key. Wire/cable mechanical shift is standard on this unit. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered output bearings replace the needle bearings found on earlier designs for greater load-bearing capability. Pro Gear and Transmission carries this genuine Chelsea unit.
