The Chelsea 489GHITX-A3GF or 489GHITXA3GF is a 489 Series Power Take-Off assembly designed for manual transmissions with an 8-bolt PTO mounting opening, including Eaton/Fuller, Volvo/Mack, and Tremec gearboxes. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating a common leak path. This unit uses a wire/cable mechanical shift and carries a 1-1/4" round output shaft with key. Intermittent torque for the 489 Series falls in the 201-300 lb-ft (301-400 Nm) range, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load capacity. Internal parts share commonality with the Chelsea 442 Series, and the kit-style design simplifies field service. Call us to confirm proper fit for your specific transmission and application.
