The Chelsea 489 Series Power Take-Off, part number 489GRITX-A3RB or 489GRITXA3RB, is a mechanical-shift PTO built for 8-bolt manual transmission openings. The integral 8-bolt cast iron housing bolts directly to compatible transmissions, including Eaton Fuller, Mack, and Tremec, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series delivers an intermittent torque rating of 201-300 lb-ft and shaft output of 24 HP at 500 RPM or 48 HP at 1,000 RPM. The output shaft is a 1-1/4 inch round keyed shaft. Strong tapered bearings replace needle bearings for greater load-bearing capability. Typical 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.
