The Chelsea 489 Series Power Take-Off Assembly, part number 489XUAHX-V3GH or 489XUAHXV3GH, mounts directly to an 8-bolt transmission opening on compatible manual transmissions including Eaton/Fuller, Volvo/Mack, and others. The one-piece cast iron housing bolts on without an adapter plate, reducing potential leak paths compared to designs that require one. Shift is wire/cable mechanical. The 1-1/4" round output shaft (with key) delivers up to 48 HP at 1,000 RPM (36 kW) and carries an intermittent torque rating in the 201-300 lb-ft range for the series; check application pages for the actual torque rating for your specific installation. Strong tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series, simplifying parts sourcing. Available in no-pressure-lube (X) or pressure-lube (P) configurations. Call us to confirm proper fit for your transmission.
