The Chelsea 489 Series Power Take-Off Assembly, part number 489KFAHX-A3XK or 489KFAHXA3XK, is a kit-style PTO built for 8-bolt manual transmission openings including Eaton Fuller, Mack, and Tremec. Its one-piece cast iron housing bolts directly to the transmission without an adapter plate, reducing potential leak paths. Shift is wire/cable mechanical. The 1-1/4" round output shaft with key delivers intermittent torque in the 201-300 lb-ft range, with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your transmission and application.
