The Chelsea 489 Series Power Take-Off Assembly, part number 489GSAHX-A5AZ or 489GSAHXA5AZ, is a kit-style PTO built around a one-piece cast iron housing that bolts directly to the 8-bolt transmission opening on compatible Eaton/Fuller, Volvo/Mack, and other manual transmissions. This unit uses a wire/cable mechanical shift and delivers up to 250 lb-ft intermittent torque, matching the torque capacity of the Chelsea 442 Series. The 1-1/4" round output shaft (with key) is backed by tapered bearings for greater load-bearing capability over needle-bearing designs. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. The kit-style design simplifies servicing, and internal parts are shared with the 442 Series. Call us to confirm proper fit for your transmission application.
