The Chelsea 489 Series Power Take-Off, part number 489GSAHX-S5XK or 489GSAHXS5XK, is a mechanical-shift PTO designed for 8-bolt manual transmission openings including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, reducing potential leak paths and mounting time. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM or 48 HP at 1,000 RPM. Output is through a 1-1/4" round shaft with key. Tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your application.
