The Chelsea 489 Series Power Take-Off, part number 489XAAHX-A5GQ or 489XAAHXA5GQ, mounts directly to 8-bolt manual transmission openings including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing eliminates a potential leak path and delivers intermittent torque in the 201-300 lb-ft range. Output is through a 1-1/4" round keyed shaft. The 489 Series uses wire/cable mechanical shift and features tapered bearings instead of needle bearings for increased load capacity. Internal parts are common to the Chelsea 442 Series, making service straightforward. Suitable for utility trucks, dump trucks, snow and ice removal, and fire and rescue applications. Call us to confirm proper fit for your specific transmission.
