The Chelsea 489 Series Power Take-Off, part number 489ZFDAX-U5XK or 489ZFDAXU5XK, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec units. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path. This unit runs a wire/cable mechanical shift and delivers a 1-1/4" round output shaft. The 489 Series carries the same 250 lb-ft intermittent torque capacity as the 442 Series, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. Internal parts are common to the 442 Series, and tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your transmission and application.
