The Chelsea 489GSAHX-V3GF or 489GSAHXV3GF is a 489 Series Power Take-Off assembly designed 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, eliminating the adapter plate and its associated leak path. This unit delivers intermittent torque in the 201-300 lb-ft (301-400 Nm) range, matching the torque capacity of the 442 Series. Output shaft is a 1-1/4" round with key. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The wire/cable mechanical shift configuration suits a wide range of cab-mounted control setups. For continuous-duty torque ratings, check the application pages for your specific installation. Call us to confirm proper fit for your application.
