The Chelsea 489XHAHX-W3RK is an 8-bolt mechanical shift Power Take-Off from the Chelsea 489 Series, designed to mount directly to the 8-bolt aperture of most manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Output is via a round shaft with a 1-1/4-inch key. Strong tapered bearings replace needle bearings for greater load-bearing capability. Available from Pro Gear and Transmission.
