The Chelsea 489GFAHX-A3RF is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec without requiring an adapter plate. The one-piece cast iron housing bolts to the 8-bolt transmission opening, eliminating a potential leak path at the adapter plate joint. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and produces up to 48 HP at 1,000 RPM via its 1-1/4" round keyed output shaft. Shift type is wire/cable mechanical. Internal parts are common to the Chelsea 442 Series. Available from Pro Gear and Transmission.
