The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-A5RB or 489XLAHXA5RB, mounts directly to an 8-bolt transmission opening without an adapter plate, which eliminates a common leak path. This air shift unit delivers an intermittent torque rating in the 201-300 lb-ft range for the series. The 489 Series supports up to 48 HP at 1,000 RPM. The one-piece cast iron housing bolts to Eaton/Fuller, Mack, Tremec, and other compatible manual transmissions. Internal parts are common to the Chelsea 442 Series, and the kit-style design simplifies bench service. Call us to confirm proper fit for your specific transmission.
