The Chelsea 489XQITX-A3RB or 489XQITXA3RB is a 489 Series Power Take-Off assembly built for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Volvo/Mack, and Tremec applications. Its one-piece cast iron housing bolts directly to the transmission opening, eliminating the adapter plate that creates an additional leak path. Shift is wire/cable mechanical. The output shaft is a 1-1/4" round shaft with key. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM and 48 HP at 1000 RPM. Tapered bearings replace needle bearings for improved load capacity. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your application.
