The Chelsea 489ZSDAX-T5SQ is an 8-bolt Power Take-Off from Chelsea's 489 Series, designed to mount directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, reducing both installation time and potential leak paths. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 48 HP at 1,000 RPM from the output shaft. Wire/cable mechanical shift operation and a 1-1/4" round keyed output shaft define the core configuration. Strong tapered bearings replace needle bearings for improved load-bearing capability.
