The Chelsea 489XCAHX-A3XX is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths and cutting installation time. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 48 HP at 1,000 RPM via a 1-1/4" round keyed output shaft. Shift is mechanical via wire or cable. Strong tapered bearings replace needle bearings for greater load-bearing capability. Common applications for this series include utility trucks, dump trucks, aerial equipment, and snow and ice removal units. Available from Pro Gear and Transmission.
