The Chelsea 489 Series Power Take-Off, part number 489KFAHX-W6XK or 489KFAHXW6XK, mounts directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the adapter plate found on older designs, reducing potential leak paths. Wire/cable mechanical shift is standard on this unit, with an electric-over-air shift option available. Output is delivered through a 1-1/4" round shaft with keyway. The 489 Series shares its internal components with the Chelsea 442 Series, providing an intermittent torque rating of 250 lb-ft (339 Nm). Shaft power output reaches 24 HP at 500 RPM and 48 HP at 1,000 RPM. Call us to confirm proper fit for your application.
