The Chelsea 489ZSDAX-A3XD or 489ZSDAXA3XD is a 489 Series Power Take-Off assembly from Parker Chelsea, 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 an extra potential leak path. This unit uses an air shift and delivers shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM, with an intermittent torque rating of 201-300 lb-ft for the series. The 1-1/4" round output shaft is available with a key. Internal parts are common to the Chelsea 442 Series, giving parts-counter staff a familiar service baseline. Call us to confirm proper fitment for your transmission and application.
