The Chelsea 489XFAHX-P3AZ or 489XFAHXP3AZ is a 489 Series Power Take-Off unit built for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec. The integral one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the need for an adapter plate and reducing potential leak paths. This unit features pressure lubrication and a wire/cable mechanical shift. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 48 HP at 1,000 RPM on the output shaft. Strong tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your application.
