The Chelsea 489XFAHX-P5RK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to manual transmissions with an 8-bolt aperture, including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, reducing mounting time and potential leak paths. This unit is configured with pressure lubrication and a 1-1/4" round keyed output shaft. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 48 HP at 1,000 RPM. Internal components are common to the Chelsea 442 Series, and the unit features tapered bearings for increased load capacity. Available from Pro Gear and Transmission.
