The Chelsea 489XSAHX-A3RF or 489XSAHXA3RF is a 489 Series power take-off assembly designed for manual transmissions with an 8-bolt PTO opening, including Eaton/Fuller, Volvo/Mack, and other compatible units. The one-piece cast iron housing bolts directly to the transmission opening without an adapter plate, eliminating a potential leak path. This unit uses a wire/cable mechanical shift and delivers 24 HP at 500 RPM and 48 HP at 1,000 RPM from a 1-1/4" round output shaft with key. Intermittent torque rating for the 489 Series is 250 lb-ft; check application pages to confirm actual torque for your specific installation. Internal parts are common to the Chelsea 442 Series.
