The Chelsea 489 Series Power Take-Off Assembly, part number 489XQAHX-V3RA or 489XQAHXV3RA, mounts directly to the 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 common leak path compared to bolt-on adapter designs. This unit uses a wire/cable mechanical shift and delivers shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM, with an intermittent torque rating in the 201-300 lb-ft range. The 1-1/4" round output shaft (with keyway) supports greaseable output options. Internal parts are shared with the Chelsea 442 Series. Call us to confirm proper fit for your transmission.
