The Chelsea 489XLAHX-V3GB or 489XLAHXV3GB is a 489 Series Power Take-Off assembly built for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission opening without an adapter plate, eliminating that extra leak path. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm), matching the 442 Series. Output shaft is a 1-1/4" round shaft with keyway. Shift actuation is wire/cable mechanical. Output power reaches 48 HP (36 kW) at 1,000 RPM. Strong tapered bearings replace the needle bearings found in some competing designs for improved load-bearing capability. A genuine Chelsea part available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
