The Chelsea 489ZXDAX-A5RF is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to 8-bolt manual transmission openings on vehicles such as Eaton Fuller, Eaton Endurant, Mack, and Tremec-equipped trucks. The one-piece cast iron housing eliminates the adapter plate found on other designs, reducing potential leak paths and cutting installation time. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP. Shift type is wire/cable mechanical. The output shaft is a 1-1/4" round shaft with key. Strong tapered bearings replace needle bearings for greater load capacity. Common applications include utility trucks, dump trucks, snow and ice removal, and fire and rescue equipment. A genuine Chelsea part sold by Pro Gear and Transmission.
