The Chelsea 489 Series Power Take-Off, part number 489XCAHX-V5RK or 489XCAHXV5RK, is an air shift PTO designed for 8-bolt manual transmission openings including Eaton Fuller, Mack, and Tremec units. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, reducing potential leak paths compared to adapter-plate designs. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft output of 24 HP at 500 RPM or 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your specific transmission and application.
