The Chelsea 489 Series Power Take-Off, part number 489ZLDAX-T5XK or 489ZLDAXT5XK, is a mechanical-shift PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating an extra potential leak path. This unit uses tapered bearings rather than needle bearings for greater load-bearing capability. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 48 HP at 1,000 RPM via a 1-1/4" round keyed output shaft. Internal parts are common to the Chelsea 442 Series, making service straightforward. Fits most manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. Call us to confirm proper fit for your application.
