The Chelsea 489 Series Power Take-Off, part number 489XQAHX-V3GA or 489XQAHXV3GA, is an 8-bolt PTO designed to mount directly to compatible manual transmissions including Eaton Fuller, Mack, and Tremec without requiring an adapter plate. The integral one-piece cast iron housing eliminates the adapter plate leak path common on other designs. The 489 Series uses wire/cable mechanical shift and delivers a 1-1/4" round keyed output shaft. Tapered bearings replace needle bearings for greater load-bearing capability, and internal parts are common to the Chelsea 442 Series. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and output power in the 46-55 HP range at the series level. Call us to confirm proper fit for your specific transmission and application.
