The Chelsea 489 Series Power Take-Off Assembly, part number 489XRAHX-A5RB or 489XRAHXA5RB, 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 adapter plate found on some competitive designs, reducing potential leak paths and cutting installation time. Wire/cable mechanical shift comes standard on this unit. Output is through a 1-1/4" round shaft (with key option available), rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm). Internal components are shared with the Chelsea 442 Series, keeping parts-counter service straightforward.
