The Chelsea 489 Series Power Take-Off Assembly, part number 489GFITX-A3XD or 489GFITXA3XD, is an 8-bolt PTO designed to mount directly to the 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, reducing potential leak paths. This unit uses a wire/cable mechanical shift and delivers up to 48 HP at 1,000 RPM through a 1-1/4" round output shaft with key. The 489 Series shares internal components with the Chelsea 442 Series and features tapered bearings rather than needle bearings for greater load capacity. Intermittent torque rating for the series is 201-300 lb-ft; consult the application pages for the exact rating for your configuration. Call us to confirm proper fit for your application.
