The Chelsea 489 Series Power Take-Off 489KRBGX-W3XD or 489KRBGXW3XD is a mechanical shift PTO designed for 8-bolt manual transmission openings, including Eaton Fuller, Eaton Endurant, Mack, and Tremec gearboxes. The one-piece cast iron housing bolts directly to the 8-bolt aperture, 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 delivers up to 48 HP at 1,000 RPM via a 1-1/4" round keyed output shaft. Tapered bearings replace needle bearings for improved load capacity. Call us to confirm proper fit for your application.
