The Chelsea 489 Series Power Take-Off, part number 489XQAHX-V3GQ or 489XQAHXV3GQ, is a mechanical-shift PTO designed for manual transmissions with an 8-bolt mounting aperture, including Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening without an adapter plate, eliminating a potential leak path. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 55 HP output. Output is via a 1-1/4" round keyed shaft. Shift is wire/cable mechanical. Internal parts share commonality with Chelsea's 442 Series, and the design uses tapered bearings rather than needle bearings for increased load capacity. A genuine Chelsea part, sold by Pro Gear and Transmission. Call us to confirm proper fit for your specific transmission.
