The Chelsea 489 Series Power Take-Off, part number 489XQAHX-A5RY or 489XQAHXA5RY, is a mechanical-shift PTO designed for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating a potential leak path. This series is rated for intermittent torque of 201 to 300 lb-ft and output power of 46 to 55 HP. The 1-1/4" round keyed output shaft and strong tapered bearings give it solid load-bearing capability across vocational applications including dump trucks, utility trucks, and snow and ice removal equipment. Call us to confirm proper fit for your transmission and application.
