The Chelsea 489 Series Power Take-Off, part number 489XLAHX-W3XQ or 489XLAHXW3XQ, is an 8-bolt PTO assembly designed for manual transmissions including Eaton/Fuller, Volvo/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 delivers up to 250 lb-ft intermittent torque and uses a wire/cable mechanical shift. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load-bearing capability. A genuine Chelsea part sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
