The Chelsea 489 Series Power Take-Off, part number 489XFAHX-U3XK or 489XFAHXU3XK, mounts directly to 8-bolt transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible manual transmissions using a one-piece cast iron housing that eliminates the need for an adapter plate, reducing potential leak paths. Shift type is wire/cable mechanical. The 1-1/4" round output shaft (with key) delivers up to 48 HP at 1,000 RPM and carries an intermittent torque rating of 250 lb-ft for the 489 Series. Strong 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.
