The Chelsea 489 Series Power Take-Off 489ZHAHX-A3RB or 489ZHAHXA3RB is an 8-bolt PTO built for most manual transmissions, including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. The series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP. Tapered bearings replace needle bearings for greater load capacity. The 1-1/4" round keyed output shaft is a standard configuration for this series. Call us to confirm proper fit for your application.
