The Chelsea 489 Series Power Take-Off 489ZRAHX-A3RB or 489ZRAHXA3RB is an 8-bolt PTO designed for manual transmissions including Eaton Fuller, Mack, and Tremec. The integral 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. This unit uses tapered bearings rather than needle bearings for increased load capacity. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP. Shift type is air shift. Call us to confirm proper fit for your specific transmission and application.
