Description
The Chelsea 489 Series Power Take-Off Assembly, part number 489GQAHX-V3AF or 489GQAHXV3AF, is a one-piece cast iron PTO built for 8-bolt transmission openings on manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec. The integral 8-bolt housing bolts directly to the transmission without an adapter plate, eliminating a potential leak path. This unit uses a wire/cable mechanical shift mechanism and delivers up to 250 lb-ft (339 Nm) intermittent torque, matching the torque capacity of the Chelsea 442 Series. Output is through a 1-1/4″ round shaft with key. Strong tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your application.
