The Chelsea 489QRLZX-D3AF is an 8-bolt Power Take-Off (PTO) from the Chelsea 489 Series, designed to mount directly to manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing bolts straight to the 8-bolt transmission opening, eliminating an adapter plate and reducing potential leak paths. Shift is accomplished via wire/cable mechanical actuation. The 489 Series carries an intermittent torque rating of 201-300 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" round keyed shaft. Common applications for the 489 Series include utility trucks, dump trucks, and snow and ice removal equipment. Pro Gear and Transmission carries this genuine Chelsea part.

Additional Information
The Chelsea 489 Series is compatible with most manual transmissions carrying an 8-bolt PTO aperture, including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The series features strong tapered bearings rather than needle bearings for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series, simplifying service and parts sourcing. Twenty-seven output options are available across the 489 Series, including Chelsea's 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Typical 489 Series applications include utility trucks, aerial equipment, dump trucks, snow and ice removal, 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.
