The Chelsea 489XCAHX-V6XD 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 both installation time and potential leak paths. The 489 Series delivers intermittent torque of 201-300 lb-ft and uses wire/cable mechanical shift. Output is through a 1-1/4" round keyed shaft. Strong tapered bearings provide greater load-bearing capacity compared to needle-bearing designs. Common applications for this series include utility trucks, dump trucks, aerial equipment, and snow and ice removal vehicles. A genuine Chelsea part, available from Pro Gear and Transmission.
