The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-V5XQ or 489XLAHXV5XQ, mounts directly to an 8-bolt transmission opening on manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing eliminates the adapter plate used in older designs, reducing potential leak paths and installation time. This unit uses a wire/cable mechanical shift and delivers output power in the 46-55 HP range. The 1-1/4" round output shaft accepts a keyed connection. Tapered bearings replace needle bearings for greater load capacity. Internal components are common to the Chelsea 442 Series. Call us to confirm proper fit for your specific transmission and application.
