The Chelsea 489 Series Power Take-Off, part number 489ZHDAX-A5GA or 489ZHDAXA5GA, is an 8-bolt mechanical shift PTO designed for most manual transmissions including Eaton Fuller, Eaton Endurant, 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 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP. Strong tapered bearings replace needle bearings for improved load capacity. The round output shaft uses a 1-1/4-inch key. Call us to confirm proper fit for your specific transmission and application.
