The Chelsea 489 Series Power Take-Off Assembly, part number 489XRAHX-A3GF or 489XRAHXA3GF, is a wire/cable mechanical shift PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the transmission face, eliminating the adapter plate and its associated leak path. The 489 Series carries an intermittent torque rating of 201-300 lb-ft (301-400 Nm) and delivers up to 48 HP at 1,000 RPM through a 1-1/4" round output shaft. Strong tapered bearings replace needle bearings for greater load capacity. Internal parts are common to Chelsea's 442 Series, and the kit-style design simplifies bench service. Compatible transmissions include Eaton Fuller, Mack, and Tremec units with an 8-bolt PTO aperture. Call us to confirm proper fit for your application.
