The Chelsea 489XCAHX-A3GZ or 489XCAHXA3GZ 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 8-bolt transmission opening, eliminating the adapter plate that creates an additional leak path. Wire/cable mechanical shift operation is standard on this unit. The 1-1/4" round output shaft (with key) delivers up to 48 HP at 1000 RPM, with an intermittent torque rating of 201-300 lb-ft for the 489 Series. Tapered output bearings handle higher radial loads than needle-bearing designs. Internal parts are common with the Chelsea 442 Series, simplifying service and parts sourcing. Available from Pro Gear and Transmission. Call us to confirm fitment for your specific transmission and application.
