The Chelsea 489XFITX-A5AF or 489XFITXA5AF is an 8-bolt Power Take-Off from Chelsea's 489 Series, designed for manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate and its associated leak path. This unit uses tapered bearings rather than needle bearings for greater load capacity. The 489 Series delivers intermittent torque of 201 to 300 lb-ft and output power of 46 to 55 HP, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Shift type is air shift. The output is an SAE B 2 or 4-bolt flange with a 1 inch 15-tooth SAE BB shaft. Call us to confirm proper fit for your application.
