The Chelsea 489 Series Power Take-Off 489XFAHX-S3XD or 489XFAHXS3XD mounts directly to an 8-bolt transmission opening on most manual transmissions, including Eaton Fuller, Mack, and Tremec units. The one-piece cast iron housing eliminates the adapter plate needed on earlier designs, removing a potential leak path. This unit uses a wire/cable mechanical shift and delivers up to 250 lb-ft intermittent torque, matching the capacity of the 442 Series. The 1-1/4" round output shaft with key accepts a wide range of hydraulic pump drives. Tapered bearings replace needle bearings for greater load-handling capability. Internal parts are common to the 442 Series, simplifying serviceability. Call us to confirm proper fit for your transmission and application.
