The Chelsea 489XRHWX-S3XK is an 489 Series Power Take-Off unit built 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 is rated for 201-300 lb-ft intermittent torque and delivers up to 46-55 HP output. Shift type is wire/cable mechanical. Output is via a 1-1/4" round keyed shaft. Strong tapered bearings replace needle bearings for greater load-bearing capability. Compatible transmission families include Eaton Fuller, Mack, and Tremec. Available from Pro Gear and Transmission.
