The Chelsea 489ZSDAX-V5AF or 489ZSDAXV5AF is a 489 Series Power Take-Off built for 8-bolt manual transmission openings, including Eaton Fuller, Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission, eliminating the adapter plate and its associated leak path. Shift type is air shift. The 489 Series carries intermittent torque ratings of 201-300 lb-ft and uses tapered bearings rather than needle bearings for increased load capacity. The output shaft is a 1-inch 15-tooth SAE BB shaft on an SAE B 2 or 4-bolt flange. Call us to confirm proper fit for your specific transmission and application.
