The Chelsea 489 Series Power Take-Off Assembly, part number 489XUBGX-A3XK or 489XUBGXA3XK, mounts directly to an 8-bolt transmission opening on compatible 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 potential leak path compared to multi-piece designs. This unit uses a wire/cable mechanical shift and delivers an intermittent torque rating characteristic of the 489 Series: 250 lb-ft (339 Nm), with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Output is through a 1-1/4" round shaft with key. Internal components are common to the Chelsea 442 Series, making parts sourcing straightforward.
