The Chelsea 489 Series Power Take-Off Assembly, part number 489XSEVX-A3XD or 489XSEVXA3XD, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec units. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths compared to designs requiring a separate mounting adapter. This unit uses a wire/cable mechanical shift and carries a 1-1/4" round output shaft with key option. Intermittent torque rating for the 489 Series is 201-300 lb-ft (301-400 Nm); shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series.
