The Chelsea 489 Series Power Take-Off 489GCAHX-A3GA or 489GCAHXA3GA is a mechanical-shift PTO built for 8-bolt manual transmission openings found on Eaton Fuller, Mack, Tremec, and Eaton Endurant gearboxes. The integral one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating a potential leak path and reducing installation time. The series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 55 HP intermittent output. Output is via a 1-1/4" round shaft with key. Tapered bearings handle radial loads more capably than needle-bearing designs. Call us to confirm proper fit for your specific transmission and application.
