The Chelsea 489 Series Power Take-Off, part number 489XRAHX-A3RK or 489XRAHXA3RK, is a mechanical-shift PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating a common leak path. The 489 Series delivers up to 250 lb-ft torque capacity, matching the Chelsea 442 Series, and uses tapered bearings rather than needle bearings for greater load capacity. Output is via a 1-1/4" round keyed shaft. This unit fits a wide range of manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. Call us to confirm proper fit for your specific transmission and application.
