The Chelsea 489 Series Power Take-Off, part number 489KFAHX-A5RK or 489KFAHXA5RK, is a mechanically shifted PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the transmission face, eliminating the adapter plate that creates an additional leak path. Strong tapered bearings replace the needle bearings common in older designs, improving load-bearing capability under demanding vocational cycles. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output shaft is a 1-1/4" round keyed design. Compatible transmission families include Eaton Fuller, Mack, Tremec, and Eaton Endurant with an 8-bolt aperture. Call us to confirm proper fit for your specific transmission and application.
