The Chelsea 489 Series Power Take-Off, part number 489XCAHX-W3XQ or 489XCAHXW3XQ, is an 8-bolt PTO assembly designed for manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening without an adapter plate, reducing mounting time and potential leak paths. Shift is accomplished via wire/cable mechanical actuation. The 1-1/4" round output shaft (with key) delivers up to 250 lb-ft intermittent torque, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. Tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series, and greaseable output options help reduce shaft spline fretting and corrosion. Call us to confirm proper fit for your transmission.
