The Chelsea 489 Series Power Take-Off Assembly, part number 489XCAHX-A6XD or 489XCAHXA6XD, mounts directly to an 8-bolt transmission opening on compatible manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths compared to multi-piece designs. This unit uses a wire/cable mechanical shift with an electric-over-air shift option also available. The 1-1/4" round output shaft accepts a key, and shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque capacity matches the 489 Series rating of 201-300 lb-ft; check application pages for your specific configuration. Internal parts are common with the Chelsea 442 Series, keeping spare parts inventory simple. Call us to confirm proper fit for your transmission and application.
