The Chelsea 489 Series Power Take-Off, part number 489XQAHX-A5RE or 489XQAHXA5RE, is a wire/cable mechanical shift PTO built for 8-bolt manual transmission openings including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, removing one potential leak path. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and uses tapered bearings rather than needle bearings for greater load capacity. Output is through a 1-1/4 inch round keyed shaft. The series supports applications such as utility trucks, dump trucks, and snow and ice removal equipment. Call us to confirm proper fit for your specific transmission and application.
