The Chelsea 489XQAHX-V5RF is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to bolt directly to manual transmission openings on Eaton Fuller, Mack, Tremec, and similar applications. The one-piece cast iron housing eliminates the need for an adapter plate, reducing mounting time and potential leak paths. Wire/cable mechanical shift is standard. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Output is via a 1-1/4" round shaft with key. Available from Pro Gear and Transmission.

Additional Information
The Chelsea 489 Series shares internal parts with the 442 Series and uses tapered bearings rather than needle bearings for greater load-bearing capability. The series offers eleven internal speed ratios and twenty-seven output options, including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Typical vocational applications include utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue vehicles.Parts Manual: Chelsea 489 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
