The Chelsea 489GHITX-A5GK or 489GHITXA5GK 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, reducing potential leak paths. This unit features a wire/cable mechanical shift, a 1-1/4" round output shaft with key, and tapered output bearings for improved load-bearing capability over needle-bearing designs. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm); shaft power output reaches 24 HP at 500 RPM and 48 HP at 1,000 RPM. Kit-style construction shares internal components with the Chelsea 442 Series, simplifying parts stocking and service. Call us to confirm proper fit for your specific transmission and application.
