Chelsea 489 Series Power Take-Off Assembly, part number 489XUEVX-A5XK or 489XUEVXA5XK, is an 8-bolt mount PTO built for manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec platforms. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift is air shift. The output is an SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Intermittent torque rating for the 489 Series is 201-300 lb-ft; check application pages for the actual rating specific to your application. Shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your transmission.
