The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-U5XK or 489XLAHXU5XK, is an 8-bolt PTO built for manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission's 8-bolt opening, eliminating the need for an adapter plate and removing a potential leak path. Output is an SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Shift is air shift with a PTO/dump pump combo valve. Intermittent torque rating for the 489 Series is 201-300 lb-ft (301-400 Nm); check application pages for the actual torque rating specific to your configuration. Shaft power output reaches 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, and the 489 Series accommodates an electric-over-air shift option. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
