The Chelsea 489 Series Power Take-Off, part number 489XQAHX-V5RK or 489XQAHXV5RK, is built for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing bolts directly to the transmission opening, eliminating the adapter plate and reducing potential leak paths. Output is through a 1-1/4" round shaft with a key drive. Shift is wire/cable mechanical. The series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for improved load capacity. Call us to confirm proper fit for your application.

Additional Information
The Chelsea 489 Series PTO shares internal components with the Chelsea 442 Series, which simplifies service parts sourcing across both platforms. The kit-style design allows for easier in-field servicing. Output options within the 489 Series include a 360-degree rotatable flange with a greaseable shaft, helping reduce pump shaft spline fretting and corrosion over time. Eleven internal speed ratios are available across the series. Typical applications include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles.
