The Chelsea 489 Series Power Take-Off, part number 489GRAHX-U5SQ or 489GRAHXU5SQ, is a wire/cable mechanical-shift PTO built for 8-bolt manual transmission apertures including Eaton Fuller, Mack, and Tremec applications. The integral 8-bolt cast iron housing bolts directly to the transmission opening without an adapter plate, which removes a potential leak path and cuts mounting time. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and up to 46-55 HP output. Tapered bearings replace needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series. Typical applications include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles.
