The Chelsea 489QFLZX-V3RY 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, Mack, and Tremec. The integral one-piece cast iron housing eliminates the need for an adapter plate, reducing installation time and potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range with output power from 46 to 55 HP, and uses wire/cable mechanical shift. Tapered bearings replace needle bearings for improved load-carrying capability. The 1-1/4" round keyed output shaft is a standard 489 Series configuration. Internal parts are common to the Chelsea 442 Series.
