The Chelsea 489 Series Power Take-Off Assembly, part number 489XHAHX-A5AZ or 489XHAHXA5AZ, mounts directly to 8-bolt manual transmission openings from Eaton Fuller, Volvo, Mack, and other compatible manufacturers. The one-piece cast iron housing bolts straight to the transmission aperture, eliminating the need for an adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical. The 1-1/4" round output shaft supports an intermittent torque rating of 201-300 lb-ft (301-400 Nm), with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load capacity. Internal parts are shared with the Chelsea 442 Series, keeping service straightforward.
