The Chelsea 489GRAHX-A5GB or 489GRAHXA5GB is a Chelsea 489 Series Power Take-Off designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the adapter plate and reducing potential leak paths. The 489 Series carries an intermittent torque rating of 201 to 300 lb-ft and uses tapered bearings for greater load-bearing capability compared to needle-bearing designs. Shift type is wire/cable mechanical. Output is via a 1-1/4" round shaft with keyway. Call us to confirm proper fit for your specific transmission and application.
