The Chelsea 489KQAHX-A5XD is an 8-bolt Power Take-Off from the Chelsea 489 Series, designed to mount directly to most manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing bolts straight to the 8-bolt transmission opening, eliminating a potential leak path. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and draws on wire/cable mechanical shift operation. Output is through a 1-1/4" round keyed shaft. Internal parts are common to the Chelsea 442 Series, and tapered bearings replace needle bearings for greater load-bearing capability. Pro Gear and Transmission carries this genuine Chelsea part.
