The Chelsea 489 Series Power Take-Off Assembly, part number 489GAAHX-H3XD or 489GAAHXH3XD, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. Its one-piece cast iron housing eliminates the adapter plate found on some installations, reducing potential leak paths. The wire/cable mechanical shift operates the unit at an intermittent torque rating of 201-300 lb-ft (301-400 Nm), with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft with key accommodates greaseable output options to reduce spline fretting. Internal components are common to the Chelsea 442 Series, and the kit-style design simplifies in-field service. Call us to confirm proper fit for your transmission application.
