489XLDUX-A3XD Chelsea 489 Series PTO Assembly

The Chelsea 489 Series Power Take-Off Assembly, part number 489XLDUX-A3XD or 489XLDUXA3XD, mounts directly to an 8-bolt transmission opening on compatible manual transmissions including Eaton Fuller, Volvo/Mack, and others. Air shift actuates the unit, and output is delivered through a 1-1/4" round shaft with key. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path. The 489 Series delivers the same intermittent torque capacity as the 442 Series (up to 250 lb-ft; check application pages for actual ratings) and uses strong tapered bearings rather than needle bearings for greater load-bearing capability. Internal parts are common to the 442 Series. Call us to confirm proper fit for your transmission and application.
