The Chelsea 489XCAHX-P3XY is an 8-bolt Power Take-Off from the Chelsea 489 Series, designed to mount directly to manual transmissions including Eaton Fuller, Mack, and Tremec without requiring an adapter plate. The one-piece cast iron housing bolts to the 8-bolt transmission opening and shares internal parts with the 442 Series. This unit features a wire/cable mechanical shift and a 1-1/4" round keyed output shaft. The 489 Series carries an intermittent torque rating of 201 to 300 lb-ft and delivers up to 48 HP at 1,000 RPM through the output shaft. Tapered bearings replace needle bearings for improved load-bearing capacity. Sold by Pro Gear and Transmission.
