The Chelsea 489XFAHX-M5RK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to manual transmissions including Eaton Fuller, Mack, and Tremec models. The one-piece cast iron housing bolts 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 up to 46-55 HP of output power. Shift type is wire/cable mechanical. Output is via a 1-1/4" round keyed shaft. Strong tapered bearings replace needle bearings for improved load-bearing capability. Available from Pro Gear and Transmission.
