The Chelsea 489 Series Power Take-Off, part number 489XSITX-S3XD or 489XSITXS3XD, is an 8-bolt PTO built for manual transmissions including Eaton Fuller, Mack, and Tremec. The integral 8-bolt cast iron housing mounts directly to the transmission opening without an adapter plate, eliminating a potential leak path. This unit uses a wire/cable mechanical shift and features tapered bearings instead of needle bearings for greater load capacity. The 489 Series delivers up to 201-300 lb-ft intermittent torque and 46-55 HP output, with a 1-1/4" round keyed output shaft. Internal parts are common to the Chelsea 442 Series, making service straightforward. Call us to confirm proper fit for your specific transmission and application.
