The Chelsea 489XQAHX-A5GY is a Chelsea 489 Series Power Take-Off (PTO) built for 8-bolt manual transmission apertures found on Eaton Fuller, Mack, Tremec, and Eaton Endurant gearboxes. The integral one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the adapter plate required on some other series and reducing potential leak paths. The 489 Series carries an intermittent torque rating of 201 to 300 lb-ft and delivers shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Output is through a 1-1/4-inch round keyed shaft. Shift type is wire/cable mechanical. Internal parts are common to the Chelsea 442 Series, simplifying serviceability. Call us to confirm proper fit for your application.

Additional Information
The Chelsea 489 Series uses strong tapered bearings in place of needle bearings for greater load-bearing capability. Twenty-seven output options are available across the series, including Chelsea's 360-degree rotatable flange with a greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios and shift options are offered across the 489 Series lineup. Common internal parts with the 442 Series make this unit straightforward to service in the field. Typical 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.
