The Chelsea 489XUAHX-A5AF is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed for most 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 type is wire/cable mechanical. The output shaft is a 1-1/4" round shaft with key. 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. Strong tapered bearings replace needle bearings for greater load-bearing capability. Common applications include utility trucks, dump trucks, and snow and ice removal equipment.
