Chelsea 489 Series Power Take-Off Assembly, part number 489GQAHX-A3RB or 489GQAHXA3RB, fits manual transmissions with an 8-bolt PTO mounting aperture, including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission opening without an adapter plate, removing a potential leak path. Intermittent torque rating for the 489 Series is 201-300 lb-ft (301-400 Nm); check the application pages for the actual rating for your specific installation. Shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output is a rotatable SAE B 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Shift is air shift. Kit-style design simplifies service, and internal parts are common with the Chelsea 442 Series. Call us to confirm proper fit for your application.
