The Chelsea 489 Series Power Take-Off Assembly, part number 489KLAHX-V3AF or 489KLAHXV3AF, 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, reducing potential leak paths and installation time. Wire/cable mechanical shift actuation comes standard, with an electric-over-air shift option also available in the 489 Series. Output is via a 1-1/4" round shaft with keyway. Intermittent torque capacity matches the 442 Series at 250 lb-ft (339 Nm). Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common with the Chelsea 442 Series, simplifying parts inventory. Call us to confirm proper fit for your transmission and application.
