The Chelsea 489 Series Power Take-Off, part number 489XLAHX-A5AZ or 489XLAHXA5AZ, is an air shift PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to compatible transmissions, including Eaton Fuller, Eaton Endurant, Mack, and Tremec, without an adapter plate, eliminating an extra leak path. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 55 HP. The output is an SAE B 4-bolt flange with a 1-1/4" 14-tooth SAE C shaft. Strong tapered bearings provide greater load-bearing capability over needle-bearing designs. Common applications include utility trucks, dump trucks, and snow and ice removal equipment. Call us to confirm proper fit for your transmission and application.
