The Chelsea 489 Series Power Take-Off 489KRAHX-A3XK or 489KRAHXA3XK is an air-shift PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, reducing potential leak paths and cutting mounting time. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and is rated for up to 55 HP intermittent output. Strong tapered bearings replace needle bearings for greater load capacity. Compatible manual transmissions include Eaton Fuller, Eaton Endurant, Mack, and Tremec. Call us to confirm proper fit for your specific transmission and application.
