The Chelsea 489 Series Power Take-Off, part number 489GLAHX-A5RY or 489GLAHXA5RY, mounts directly to 8-bolt manual transmission openings on applications including Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing bolts straight to the transmission without an adapter plate, removing a potential leak path and reducing installation time. This unit uses an air shift and delivers intermittent torque in the 201-300 lb-ft range with output power of 46-55 HP. The output shaft is a DIN 5462 B8x32x36 shaft on a rotatable DIN 5462 pump mount. Strong tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your specific transmission and application.
