The Chelsea 489XCAHX-A3GB or 489XCAHXA3GB 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, eliminating the need for an adapter plate and reducing potential leak paths. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm), with shaft power of 24 HP at 500 RPM and 48 HP at 1000 RPM. This unit ships with a wire/cable mechanical shift configuration and a 1-1/4" round output shaft with keyway. The 489 Series uses tapered bearings rather than needle bearings for greater load capacity. Call us to confirm proper fit for your transmission application.
