The Chelsea 489XHITX-A3RK or 489XHITXA3RK is a Power Take-Off unit from Chelsea's 489 Series, built for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating a common leak path. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP, with a wire/cable mechanical shift. The round output shaft uses a 1-1/4" keyed configuration. Strong tapered bearings replace the needle bearings found in some earlier designs for improved load capacity. Compatible transmissions include Eaton Fuller, Eaton Endurant, Mack, and Tremec. Call us to confirm proper fit for your specific transmission and application.
