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 is through an SAE B 2 or 4-bolt flange with a 1" 15-tooth SAE BB shaft. This unit has no shift assembly (ordered without a shifter). 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. Call us to confirm proper fit for your application.
