The Chelsea 489 Series Power Take-Off Assembly, part number 489GUAHX-A3RB or 489GUAHXA3RB, is an 8-bolt PTO designed for manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate and reducing potential leak paths. Shift is wire/cable mechanical. The output shaft is a 1-1/4" round with key. The 489 Series uses tapered bearings rather than needle bearings for greater load capacity, and internal parts are common to the Chelsea 442 Series. Intermittent torque capacity for the 489 Series is 201-300 lb-ft; check application pages for the actual torque rating for your specific configuration.
