The Chelsea 489 Series Power Take-Off, part number 489XRAHX-A3RY or 489XRAHXA3RY, is a mechanical-shift PTO designed for 8-bolt manual transmission openings on applications including Eaton Fuller, Mack, and Tremec transmissions. The one-piece cast iron housing bolts directly to the 8-bolt aperture, eliminating the adapter plate that creates an additional potential leak path. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP, with tapered bearings in place of needle bearings for increased load-bearing capability. The 1-1/4" round keyed output shaft is a standard feature of this series. Call us to confirm proper fit for your specific transmission and application.
