The Chelsea 489 Series Power Take-Off, part number 489GLAHX-V5GY or 489GLAHXV5GY, is a mechanical-shift PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, cutting installation time and reducing potential leak paths. The 489 Series fits most major manual transmissions including Eaton Fuller, Mack, and Tremec. Strong tapered bearings replace needle bearings for greater load capacity. The series carries an intermittent torque rating of 201-300 lb-ft and shaft power of 24 HP at 500 RPM or 48 HP at 1,000 RPM. Output shaft type is a 1-1/4 inch round shaft with key. Common applications include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles. Call us to confirm proper fit for your application.
