The Chelsea 489 Series Power Take-Off Assembly, part number 489XQITX-A3RA or 489XQITXA3RA, 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 at the mounting face. 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 in the 201-300 lb-ft range for this series. Strong tapered bearings replace needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series, simplifying parts sourcing. Call us to confirm proper fit for your specific transmission and application.
