The Chelsea 489GHAHX-A5RB or 489GHAHXA5RB is a 489 Series Power Take-Off assembly designed for manual transmissions with an 8-bolt PTO mounting opening, including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating an extra leak path. Intermittent torque rating for the 489 Series is 250 lb-ft (339 Nm); continuous-duty applications should de-rate 30% per Chelsea application guidelines. Shift is wire/cable mechanical. The 1-1/4" round output shaft (with key option) delivers up to 48 HP at 1,000 RPM. Tapered output bearings replace the needle bearings found in some competitive designs. Internal components share commonality with the Chelsea 442 Series, making parts sourcing straightforward. Call us to confirm proper fit for your specific transmission.
