The Chelsea 489XSAHX-A3GB is an 8-bolt power take-off from the Chelsea 489 Series, designed to mount directly to manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing eliminates a common leak path and delivers the same 250 lb-ft torque capacity as the 442 Series. Shift is wire/cable mechanical. The output shaft is a 1-1/4" round keyed shaft. Strong tapered bearings replace needle bearings for greater load-bearing capability. A genuine Chelsea part from Pro Gear and Transmission.
