The Chelsea 489 Series Power Take-Off Assembly, part number 489XREVX-A5XK or 489XREVXA5XK, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing eliminates the adapter plate leak path common on earlier designs. Shift is wire/cable mechanical. Output shaft is a 1-1/4" round with key. Intermittent torque rating for the 489 Series is 201-300 lb-ft; shaft power measures 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal components are shared with the Chelsea 442 Series, simplifying parts stocking. Tapered output bearings replace needle bearings for improved load capacity.
