The Chelsea 489 Series Power Take-Off, part number 489GUAHX-W3GF or 489GUAHXW3GF, mounts directly to an 8-bolt transmission opening on most manual transmissions, including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths compared to designs requiring separate adapters. This unit uses a wire/cable mechanical shift and delivers a 1-1/4" round keyed output shaft. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and draws on 11 internal speed ratios across 27 output options. Strong tapered bearings replace needle bearings for improved load capacity. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your application.
