The Chelsea 489 Series Power Take-Off, part number 489XRAHX-A3GA or 489XRAHXA3GA, is an 8-bolt PTO assembly designed for manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. 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. This unit uses a wire/cable mechanical shift and delivers shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM, with an intermittent torque rating in the 201-300 lb-ft range. The 1-1/4" round output shaft accepts a keyed connection. Strong tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your specific transmission.
