The Chelsea 489GSAHX-A3RB or 489GSAHXA3RB is a Power Take-Off unit from Chelsea's 489 Series, designed for manual transmissions with an 8-bolt PTO mounting aperture. The one-piece cast iron housing bolts directly to the transmission opening without an adapter plate, eliminating a potential leak path. This series uses wire/cable mechanical shift and features a 1-1/4" round keyed output shaft. Tapered bearings provide greater load capacity compared to needle-bearing designs, and internal parts are common to the Chelsea 442 Series. The 489 Series covers applications including utility trucks, dump trucks, and snow and ice removal equipment. Call us to confirm proper fit for your application.
