The Chelsea 489XHITX-W3XD or 489XHITXW3XD is a 489 Series Power Take-Off assembly built for 8-bolt manual transmission openings on Eaton Fuller, Volvo, Mack, and other compatible transmissions. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, removing a potential leak path. Shift type is wire/cable mechanical. The 1-1/4" round output shaft accepts a key and delivers up to 48 HP at 1,000 RPM (24 HP at 500 RPM). Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm). Internal parts are common with the Chelsea 442 Series. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 489 Series is suited for utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue vehicles. The 489 Series features tapered bearings in place of needle bearings for greater load-bearing capability and offers 27 output options including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios are available across the series. Internal parts are interchangeable with the Chelsea 442 Series, keeping your parts inventory straightforward.
