The Chelsea 489GRAHX-S3XK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed for manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing mounts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series uses tapered bearings rather than needle bearings for greater load-bearing capability. Shift type is wire/cable mechanical. Output shaft is a 1-1/4" round shaft with keyway. Intermittent torque capacity for the series is 201-300 lb-ft. Typical applications include utility trucks, dump trucks, aerial equipment, and snow and ice removal vehicles.
