The Chelsea 489 Series Power Take-Off, part number 489XRAHX-A6RY or 489XRAHXA6RY, is an 8-bolt PTO designed for most manual transmissions including Eaton Fuller, Eaton Endurant, 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 a wire/cable mechanical shift and delivers intermittent torque in the 201-300 lb-ft range. Output is through a 1-1/4 inch round key shaft. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. Strong tapered bearings replace needle bearings for greater load capacity. Call us to confirm proper fit for your application.
