The Chelsea 489XLAHX-A5GH or 489XLAHXA5GH is a 489 Series Power Take-Off built for 8-bolt manual transmission apertures, including Eaton Fuller, Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission opening, removing the need for an adapter plate and reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and this unit runs an air shift. Output is through a greaseable SAE B 2-bolt flange with a 1" 15-tooth SAE BB shaft. Tapered bearings replace needle bearings for greater load-bearing capability. A genuine Chelsea part, sold by Pro Gear and Transmission.
