489XFDAX-A6RB Chelsea 489 Series PTO

The Chelsea 489 Series Power Take-Off, part number 489XFDAX-A6RB or 489XFDAXA6RB, is an air shift PTO designed for manual transmissions with an 8-bolt mounting aperture, including Eaton Fuller, Mack, and Tremec. The integral 8-bolt cast iron housing bolts directly to the transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series carries an intermittent torque rating of 201 to 300 lb-ft and delivers up to 46 to 55 HP output power. Tapered bearings replace needle bearings for greater load capacity. The output is a rotatable SAE B 4-bolt flange with a 7/8-inch 13-tooth SAE B shaft. Call us to confirm proper fit for your application.
