The Chelsea 489 Series Power Take-Off Assembly, part number 489ZRDAX-V5RB or 489ZRDAXV5RB, mounts directly to an 8-bolt transmission opening on compatible Eaton Fuller, Volvo, Mack, and other manual transmissions. Its one-piece cast iron housing eliminates the adapter plate found on earlier designs, reducing potential leak paths and cutting installation time. The 489 Series delivers intermittent torque in the 201-300 lb-ft (301-400 Nm) range and an output power of 46-55 HP (31-40 kW). Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. This unit uses a wire/cable mechanical shift and features a 1-1/4" round output shaft. Strong tapered bearings replace needle bearings for improved load capacity. Call us to confirm proper fit for your specific transmission and application.
