The Chelsea 489GSAHX-P3XD or 489GSAHXP3XD is a 489 Series power take-off assembly built for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the 8-bolt opening without an adapter plate, eliminating a potential leak path. This unit uses a wire/cable mechanical shift and features a 1-1/4" round output shaft with key. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm); shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Internal parts share commonality with the Chelsea 442 Series, keeping service inventory simple.
