The Chelsea 489GWAHX-A3XD or 489GWAHXA3XD 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 8-bolt opening, eliminating the need for an adapter plate and reducing potential leak paths. This unit delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft with key suits a wide range of pump connections. Tapered bearings provide greater load capacity than needle-bearing designs. Call us to confirm proper fit for your specific transmission and application.
