The Chelsea 489XRAHX-A6RK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to manual transmission openings on vehicles including Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing eliminates the need for an adapter plate, reducing both installation time and potential leak paths. Shift is wire/cable mechanical. The 1-1/4" round keyed output shaft supports greaseable output options to help prevent spline fretting and corrosion. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and shares internal components with the Chelsea 442 Series. Typical applications include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles.
