The Chelsea 489 Series Power Take-Off Assembly, part number 489GUAHX-A3AF or 489GUAHXA3AF, mounts directly to the 8-bolt transmission opening on most manual transmissions, including Eaton Fuller, Mack, and Tremec, using a one-piece cast iron housing that eliminates the adapter plate and reduces potential leak paths. Shift is wire/cable mechanical. The 1-1/4" round output shaft accepts a key, and the series supports up to 250 lb-ft intermittent torque with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common with the Chelsea 442 Series, which simplifies parts sourcing. Call us to confirm proper fit for your transmission and application.
