The Chelsea 489 Series Power Take-Off Assembly, part number 489XHAHX-V3RA or 489XHAHXV3RA, 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 potential leak path compared to traditional multi-piece designs. Intermittent torque capacity matches the Chelsea 442 Series at 250 lb-ft (339 Nm). Output shaft is a 1-1/4" round with key. Shift is wire/cable mechanical, with an electric-over-air shift option also available. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the 442 Series, simplifying parts sourcing. Call us to confirm proper fit for your transmission and application.
