Chelsea 489 Series PTO Assembly part number 489GCAHX-A5XQ or 489GCAHXA5XQ is a wire/cable mechanical shift power take-off built around an 8-bolt mounting configuration. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening on most manual transmissions, including Eaton Fuller, Eaton Endurant, Mack, and Tremec, eliminating the need for an adapter plate and the extra leak path that comes with one. The 489 Series delivers intermittent torque in the 201-300 lb-ft range, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft with key and tapered bearing design provides load-bearing capability beyond typical needle-bearing units. Internal parts are common to the Chelsea 442 Series, and greaseable output options help reduce shaft spline fretting and corrosion over time. A genuine Chelsea part, sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
