The Chelsea 489XQAHX-X3XX is an 8-bolt mechanical shift Power Take-Off from the Chelsea 489 Series, designed to mount directly to manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec without requiring an adapter plate. The one-piece cast iron housing eliminates a potential leak path and delivers the same torque capacity as the 442 Series at 250 lb-ft. Tapered bearings replace needle bearings for greater load-bearing capability. The 489 Series offers eleven internal speed ratios and twenty-seven output options, including a 360-degree rotatable flange with a greaseable 1-1/4-inch round keyed output shaft. Typical applications include utility trucks, dump trucks, aerial equipment, and snow and ice removal vehicles.
