The Chelsea 489GHAHX-T5XD is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed for manual transmissions including Eaton Fuller, Mack, and Tremec applications. 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. This series uses tapered bearings in place of needle bearings for greater load-bearing capability. Shift type is wire/cable mechanical. The output shaft is a 1-1/4" round keyed shaft. Intermittent torque rating for the 489 Series ranges from 201 to 300 lb-ft. Common applications include utility trucks, dump trucks, aerial equipment, and snow and ice removal vehicles.
