The Chelsea 489 Series PTO Assembly, part number 489GAAHX-V3GA or 489GAAHXV3GA, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing eliminates the need for an adapter plate, removing a common leak path. Shift type is air shift. The 489 Series supports intermittent torque in the 201-300 lb-ft range, with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series, simplifying parts sourcing and service.
