The Chelsea 489 Series Power Take-Off, part number 489QHLZX-D3AZ or 489QHLZXD3AZ, 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 opening, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series uses tapered bearings for greater load-bearing capability compared to needle-bearing designs. The 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. Wire/cable mechanical shift operation and internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your specific transmission and application.
