The Chelsea 489GSAHX-V3GA or 489GSAHXV3GA is a 489 Series Power Take-Off Assembly designed for 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, eliminating a potential leak path. Shift is wire/cable mechanical. The 1-1/4" round output shaft (with key) delivers up to 250 lb-ft intermittent torque and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series, and greaseable output options help reduce pump shaft spline fretting and corrosion. Call us to confirm proper fit for your application.
