The Chelsea 489XHITX-H3AF or 489XHITXH3AF is a 489 Series Power Take-Off assembly designed for manual transmissions with an 8-bolt PTO opening, including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating a potential leak path. This unit has no shift assembly and carries an intermittent torque rating of 201-300 lb-ft (301-400 Nm) for the series, with 250 lb-ft cited as the comparable torque capacity. Output shaft is an SAE B 2 or 4-bolt flange configuration with a 1" 15-tooth SAE BB shaft. Shaft power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load capacity. Call us to confirm proper fit for your application.
