The Chelsea 489QRLZX-D3RJ is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed for manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift is wire/cable mechanical. Output is through a 1-1/4" round keyed shaft, with intermittent torque capacity of 201-300 lb-ft. Tapered bearings replace needle bearings for stronger load-bearing capability. Common applications include utility trucks, dump trucks, fire and rescue, and snow and ice removal equipment.

Additional Information
The Chelsea 489 Series shares internal components with the 442 Series, making service parts interchangeable between the two families. The 489 Series offers eleven internal speed ratios and twenty-seven output options, including a 360-degree rotatable flange with a greaseable shaft to reduce pump shaft spline fretting and corrosion. Kit-style construction allows individual internal components to be serviced without replacing the full assembly.
