The Chelsea 489XLAHX-V5RK or 489XLAHXV5RK is a Power Take-Off assembly from the Chelsea 489 Series, designed for manual transmissions with an 8-bolt PTO mounting aperture. The one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and this unit uses air shift actuation. Output is through a rotatable SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Tapered bearings replace needle bearings for greater load-bearing capability. Compatible with manual transmissions including Eaton Fuller, Mack, and Tremec.
