The Chelsea 489 Series Power Take-Off, part number 489XSAHX-A5XY or 489XSAHXA5XY, is a mechanical-shift PTO designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec gearboxes. The integral 8-bolt cast iron housing bolts directly to the transmission opening without an adapter plate, eliminating a potential leak path. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP. Strong tapered bearings replace needle bearings for greater load-bearing capability. Shift is via wire/cable mechanical actuation. Call us to confirm proper fit for your application.
