The Chelsea 489 Series Power Take-Off, part number 489XRAHX-A5GZ or 489XRAHXA5GZ, is an 8-bolt air shift PTO designed for most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift is air shift. Output is through a greaseable SAE B 4-bolt flange with a 1-1/4-inch 14-tooth SAE C shaft. The 489 Series uses tapered bearings rather than needle bearings for greater load-bearing capability. Intermittent torque rating for the series is 201-300 lb-ft. Call us to confirm proper fit for your application.
