The Chelsea 489GCAHX-A5XD or 489GCAHXA5XD 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 integral one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the adapter plate and reducing potential leak paths. This unit uses an air shift and features a 1-1/4" round output shaft with keyway. Intermittent torque capacity for the 489 Series is 250 lb-ft, matching the 442 Series, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace the needle bearings found in some earlier designs, improving load-bearing capability. Internal components are common to the Chelsea 442 Series, simplifying parts sourcing and service. Call us to confirm proper fit for your specific transmission.
