The Chelsea 489XLAHX-A5GZ or 489XLAHXA5GZ is a 489 Series Power Take-Off unit designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec gearboxes. The integral 8-bolt cast iron housing bolts directly to the transmission opening, eliminating 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 uses air shift actuation. Output is through a greaseable SAE B 4-bolt flange with a 1-1/4" 14-tooth SAE C shaft. Tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your application.
