The Chelsea 489 Series Power Take-Off 489XRAHX-P3AK or 489XRAHXP3AK mounts directly to the 8-bolt transmission opening on most manual transmissions, including Eaton Fuller, Mack, and Tremec, eliminating the need for a separate adapter plate and reducing potential leak paths. The one-piece cast iron housing shares internal parts with the Chelsea 442 Series and uses tapered bearings rather than needle bearings for greater load-bearing capability. This unit features 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.
