The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-A6XD or 489XLAHXA6XD, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo, Mack, and others. Its one-piece cast iron housing eliminates the adapter plate required on many competing designs, reducing potential leak paths. The air shift delivers intermittent torque in the 201-300 lb-ft range, with an application-specific rating of 250 lb-ft. The 1-1/4" round output shaft with key accepts a wide range of hydraulic pump and accessory drives. Shaft power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal components are common with the Chelsea 442 Series, simplifying parts sourcing and service. Call us to confirm proper fit for your transmission.
