The Chelsea 489 Series Power Take-Off, part number 489GFITX-A5RA or 489GFITXA5RA, is an 8-bolt PTO assembly designed for manual transmissions including Eaton Fuller, Volvo, Mack, and Tremec. The one-piece cast iron housing bolts directly to the transmission's 8-bolt opening, eliminating the adapter plate and its associated leak path. Shift type is wire/cable mechanical. The 1-1/4" round output shaft (keyway option available) delivers up to 48 HP at 1,000 RPM, with an intermittent torque rating of 201-300 lb-ft for the series. Strong tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common with the 442 Series. Call us to confirm proper fit for your application.
