489ZFDAX-W5RB Chelsea 489 Series PTO Assembly

The Chelsea 489 Series Power Take-Off Assembly, part number 489ZFDAX-W5RB or 489ZFDAXW5RB, mounts directly to an 8-bolt transmission opening on compatible manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path. Shift is wire/cable mechanical. The 489 Series supports intermittent torque in the 250 lb-ft range and shaft power of 24 HP at 500 RPM or 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your application.
