The Chelsea 489 Series Power Take-Off Assembly, part number 489XSAHX-A5XK or 489XSAHXA5XK, mounts directly to 8-bolt manual transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible transmissions without an adapter plate. The one-piece cast iron housing delivers the same intermittent torque capacity as the 442 Series, rated at 201-300 lb-ft (301-400 Nm) for intermittent duty. For continuous duty, de-rate the torque rating by 30% and check application pages for confirmed figures. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output shaft is a 1-1/4" round configuration. Strong tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your transmission and application.
