The Chelsea 489 Series Power Take-Off Assembly, part number 489ZQDAX-A3SQ or 489ZQDAXA3SQ, mounts directly to an 8-bolt transmission opening with a one-piece cast iron housing that eliminates the need for an adapter plate, reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. This unit uses an air shift and carries an SAE B 4-bolt flange output with a 7/8" 13-tooth SAE B shaft. Compatible transmissions include Eaton/Fuller, Mack, and Tremec manual units. Tapered bearings replace needle bearings for improved load capacity. Internal parts are common to the Chelsea 442 Series, and greaseable output options help resist spline fretting and corrosion. Call us to confirm proper fit for your specific transmission.
